In primary hyperparathyroidism see Primary Hyperparathyroidism , there is excess production of parathyroid hormone PTH by an autonomous functional lesion in the parathyroid gland. The normal control mechanisms for PTH secretion by the concentration of blood calcium are lost, and the parathyroid produces excess PTH despite increased levels of blood calcium. This disease is encountered infrequently in older dogs, and it does not appear to be a sequela of renal secondary hyperparathyroidism see Renal Secondary Hyperparathyroidism. PTH acts on cells of the renal tubules initially to promote the excretion of phosphorus and retention of calcium. Mineral is removed from the skeleton and replaced by immature fibrous connective tissue.
Clinical signs include stunted growth, weakness, polyuria, polydipsia, and a diffuse reduction in bone density. The parathyroid glands may be damaged or inadvertently removed during thyroid breds. Diagnosis of Rubber Jaw Syndrome in Dogs. The increased PTH levels also inhibit the renal tubular resorption of phosphorus. Inflammation of the parathyroid glands, throat cancer, and canine distemper virus can also cause hypoparathyroidism. Yes No.

Rubber jaw syndrome is caused by hyperparathyroidism due to renal failure. The parathyroid glands are activated because of a reduction of calcium in the blood. In addition, the PTH causes the calcium to be absorbed into the intestine and consequently, the inability to activate Vitamin D3. Because of the lost calcium, the bone gets replaced by fibrous tissue and this makes the bones weak.
The amount of deformity depends on the length of time the kidneys have not been functioning right and how severe the disease is.
Rubber jaw syndrome renal osteodystrophy is a condition of excess parathyroid hormone caused by kidney disease. The kidneys are unable to excrete the parathyroid hormone, which causes a buildup of these hormones in the body.
This may be caused by primary hyperparathyroidism or secondary hyperparathyroidism. The early symptoms include depression, frequent urination, and increased thirst.
If these signs are missed, the deformity of the facial bones will soon be obvious enough to warrant a trip to the veterinarian. Some of them include large and giant breed dogs that grow rapidly such as:. To diagnose rubber jaw syndrome, your veterinary care provider will need to perform a complete and thorough physical examination even if your dog has obvious deformities and softening of the jaw.
The veterinarian will also need to run some diagnostic tests. Some of the tests should include x-rays to check the bones. In addition, an ultrasound or CT scan will show the kidneys are shrunken and have lesions. The veterinarian may also take a biopsy of the kidneys to determine the cause of kidney disease or failure. Treatment options for rubber jaw syndrome caused by renal secondary hyperparathyroidism include management of the renal disease, medication, and changes in diet.
Treatment of the renal disease should be taken care of first. However, if the kidneys are already too damaged, dialysis and a kidney transplant may be the only choice.
However, kidney transplants are rarely successful because of the unique immune system in dogs. The donor would have to be a relative of your dog and they both must be young and otherwise healthy. Calcitriol vitamin D3 should be given intravenously to regulate the blood levels of calcitriol before using oral supplements. Antibiotics may also be given if the veterinarian suspects a kidney infection.
Your dog may also need fluids and oxygen therapy so your veterinarian will probably recommend a brief hospital stay. Phosphorous binding supplements aluminum hydroxide, calcium carbonate, or sevelamer hydrochloride to control the phosphorous levels absorbed in the intestines. These tests should be done once a week for several weeks and then once per month for six months.
This is essential to prevent hypercalcemia. The veterinarian will then need to run blood tests every six weeks for about one year.

There's a great article from Dr. Tony Johnson, DVM , who explains why dogs should always be trained for muzzles and why in some cases they are required. In the end, he makes a great point about using muzzles on dogs:. Medical conditions , like brain tumors in dogs, can also cause a friendly canine to turn aggressive and become dangerous. No matter what the reason, it's likely that your dog will need to be muzzled at some point in his life.
Soft dog muzzles are usually made of mesh or nylon. You have to adjust these muzzles much tighter than basket muzzles, which restricts the ability of the dog to pant or drink water. Essentially, both types of dog muzzles accomplish the same goal. If a muzzle is too loose, it's not going to contain your dog the way it is supposed to. If it's too tight, it may restrict breathing and panting of the dog.
A muzzle that is too tight may also causing chaffing and irritation. Beginning on the top of his snout, wrap the fabric tape measure around your dog's cheek, down under his chin, and back up to the top of the snout. Measure from the eye line to the back of your dog's head behind his ears. This will tell you the length of strap that you'll need to look for.
Simply wrap the tape measure around his neck. While we include some of the best dog muzzles sold on Amazon and the prices are generally lower online than in brick-and-mortar pet stores, generally it's best to shop for a dog muzzle at your local pet store. This way you can try on the muzzle before purchasing. Nevertheless, if you choose to order a dog muzzle online, then make sure that it fits the measurements you've taken of your dog, and read reviews from other owners.
A muzzle must be used sparingly on dogs and only for situations that pose the risk of your dog biting other people or pets. Choose the basket-style when your dog needs to engage in physical or off-leash activities, such as running or playing. Well-ventilated, light and Well-fitting, comfortable Dog snout measurements The middle adjustable muzzle This design allows the dog to pant and be comfortable even when being restrained.
The snout length is 3. This muzzle is highly secure, according to dog owners that needed a really well-made muzzle for their dogs. It does allow for panting, which is important when the dog is physically active. This feature solves the problem of many dog owners whose dogs have the disgusting habit of picking or eating dirt — and worse, even feces — in parks and public places.
It's a good strong leather muzzle — just don't buy it thinking your dog can have a sip of water when thirsty. When visiting the vet or going places while your dog is leashed, the mesh style muzzle is a good option. It is softer around the snout and allows a wider area to breath because of the type of material used. The Canine Friendly Short Snout dog muzzle comes in four sizes. Made from breathable mesh and Adjustable slider and easy to Makes muzzling quick and Soft bumpers that prevent the Size Medium fits a head The mesh encloses the whole face up to the forehead with an opening around the nose.
The mesh webbing has adequate spacing so as not to obscure vision and padded bumpers to keep it off the eyes. The Canine Friendly Short Snout Dog Muzzle is the best option for dog breeds with shorter snouts and is an important addition to first aid kits for canines. The mesh keeps the dog under control without constricting his facial structure — it still allows breathing through the mouth with the tongue out and licking water in a dish. For situations that call for brief muzzling, this should serve the purpose perfectly.
I have to return the large and get an x-large to fit my bulldog. Rubber basket-style muzzles are probably the best choice when you want optimum safety with the highest level of comfort for your pet. The Company of Animals Baskerville Ultra Muzzle is made of high-quality rubber molded to a basket shape. This muzzle is available in six sizes and in colors of tan and black.
Many dog owners attest that the Company of Animals Baskerville 5-Inch Rubber Ultra Muzzle has been a real lifesaver not only for their dog, but for other dogs as well.
This may not be the solution that ends all dog fighting or socialization issues, but it has been a very useful tool for going through behavioral therapy and rehabilitation. The size chart and training guide are very important in picking out the right size and getting your dog acquainted with the muzzle. It took pet owners a little while to train their dogs to tolerate the muzzle, but they eventually took to it much better than they did previous types. Owners say that this acceptance is largely due to bigger snout space for breathing and eating, softer material used, and much wider webbing than found of some of the other animal muzzles.
Cesar Millan specially designed these muzzles to inject positive energy into situations that brought pet owners to their decision to muzzle up their dogs in the first place. Dogs are affected by negative energies, not solely coming from the canines but largely from their humans. These Cesar Millan muzzles come in dragon, smile, and braces patterns that elicit smiles and relaxed feelings in situations where their dog may injure other dogs, pets or humans.
Breathable mesh for comfort Adjustable straps in four Hand wash with cold water Dog owners who hate to muzzle their pups but must comply with requirements in many public places, were very happy that they found the Cesar Millan Funny Muzzle. They say that it lightens the mood in many situations where their dogs need to interact with people. The small size and relaxed demeanor make this a perfect little dog for apartment living.
Bred for the sole purpose of companionship, the Shih Tzu is a perfect friend and lap dog. Due to its delicate nature, it does not do well outside, especially in extreme temperatures, and must be kept inside and allowed to sleep inside. Additionally, the owner should monitor it whenever it is outside for signs of heat exhaustion. Their small size makes them perfect apartment dwellers, and they only require a short walk each day or could make do once in a while with a zoom around their rooms and under your feet.
This breed is playful and sometimes mischievous. Additionally, this breed does not always have the same separation anxiety as other toy breeds, and if left alone for a few hours, should peacefully play with toys or run around the house until you return.
They have a long, shaggy or silky double coat which comes in many different colors. In show Shih Tzu, it is common for owners to allow their fur to grow long and trim it until it skims the ground, which is an interesting and beautiful cut. Their beautiful coat, regardless of its length, requires daily brushing and regular and frequent grooming. Be sure to comb out any tangles before a bath , as the water will tighten these tangles and make them nearly impossible to remove.
Shih Tzu also have a distinctive topknot on their heads, which can be cut or tied into a small bun with a tie made specifically for hair or fur. Although their coat is relatively-shed free , they are not an entirely hypoallergenic breed. Additionally, when they are about one year old, they go through an intense shedding phase for about three weeks that may startle a new owner , but this is typical and should taper off naturally as they grow their adult coat.
The average Shih Tzu lifespan is approximately 13 years but can range from ten to sixteen years, although this time may not be free from health conditions. Their small size may manifest itself in different health issues , including dental complications, dislocated kneecaps, and respiratory problems.
They may also be prone to obesity. Additionally, while adopting an adult Shih Tzu from a shelter may not ensure that they will not have these issues, you will at least be able to prepare yourself by knowing if they do, as these should manifest before adulthood.
Wherever you source your Shih Tzu, you will be welcoming a perky lap dog who will bring lots of smiles to your life as you groom and play with your dog.
Also see professional content regarding disorders associated with calcium, phosphorus and Vitamin D. Defective bone formation is called osteodystrophy. The primary source of calcium and phosphorus is the diet, but a number of factors affect how the body absorbs calcium and phosphorus.
These include the source of the minerals as well as the levels of vitamin D in the body. Vitamin D is obtained either through the diet or by exposure to sunlight. Abnormalities of the bones can result, as well as other nutritional and metabolic complications. Rickets is a rare disease of young, growing animals that causes soft and deformed bones.
It is commonly caused by insufficient phosphorus or vitamin D in the diet. An excess of calcium has caused rickets-like signs in some dogs. Animals fed all-meat diets commonly develop rickets. Signs may include bone pain and swelling, a stiff gait or limp, difficulty in rising, bowed limbs, and fractures.
Affected puppies may become quiet and reluctant to play. Touching the bones will cause pain, and folding fractures of long bones and vertebrae are common. X-rays will show distortions in the bone. In advanced cases, limbs can be deformed due to the bones growing at unequal rates. The outlook for treating rickets is good if there are no broken bones or irreversible damage to the bone. The primary treatment is to correct the diet.
Exposure to sunlight ultraviolet radiation will also increase the production of vitamin D. Osteomalacia develops similarly to rickets but in mature bones. Affected animals may fail to thrive and may crave and eat substances such as paint chips, clay, plaster, or dirt. Deformities may also be seen in the spine, including an abnormal inward curving of the spine in the lower area of the back lordosis or an abnormal outward curving of the spine kyphosis. Affected animals should be confined for the first few weeks while the diet is corrected.
The response to proper nutrition is rapid. Jumping or climbing must be prevented because the skeleton is still susceptible to fractures. Response to treatment can be monitored using x-rays. Two metabolic disorders in dogs produce rubber jaw syndrome: primary hyperparathyroidism and hyperparathyroidism due to kidney disease. In primary hyperparathyroidism, the parathyroid gland produces too much parathyroid hormone. The disease occurs infrequently in older dogs. When too much parathyroid hormone is released over a long period of time, minerals are leached from the skeleton and replaced by immature fibrous connective tissue.
This condition, called fibrous osteodystrophy , affects the entire skeleton but tends to concentrate in the bones of the skull. Dogs with primary hyperparathyroidism may become lame and develop fractures of the long bones after minor physical trauma. Compression fractures in the spine place pressure on the spinal cord, which may disable motor and sensory functions. In some cases the condition causes a thickening of facial bones.
Nasal cavities may be damaged and teeth loosened. Some dogs lose the ability to close the mouth properly and develop slow-healing sores in the gums. Tests on animals with primary hyperparathyroidism will show an abnormally high level of calcium in the blood. Other tests can be performed to determine phosphorus and parathyroid hormone levels. The goal of treatment is to eliminate the source of excessive parathyroid hormone production.
If a tumor is causing the increased parathyroid hormone levels, it must be removed. If high levels of calcium persist a week or longer after surgery or recur after initial improvement, a second tumor or the spread of cancer from a malignant tumor may be causing the problem. The lowered calcium level in turn triggers an increase in parathyroid hormone levels. In addition, the kidneys are necessary to produce the active form of vitamin D calcitriol.
Signs of kidney disease may be seen, including vomiting, dehydration, and increased thirst or urination. Severely defective fibrous bone formation may accompany advanced kidney failure.
Excessive growth or thickening of bone tissue, such as facial swelling, may be seen in younger dogs. Long bones are less dramatically affected, but lameness, stiff gait, and fractures after minor trauma may occur.
Lab work will also reveal increased levels of parathyroid hormone in the blood. Treatment options include modifying the diet, supplementing it with active vitamin D calcitriol , and giving medication that binds phosphate.
Any underlying kidney disease must be managed as well. Prescription diets with restricted dietary phosphorus are available. Your veterinarian can give you specific recommendations for proper treatment options for your pet. Be sure to follow those recommendations and any prescriptions precisely as directed. In hypoparathyroidism, either lower than normal amounts of parathyroid hormone are secreted or the hormone secreted is unable to function normally.
This, in turn, affects the levels of calcium and phosphorus. Smaller breeds such as Miniature Schnauzers are particularly susceptible, but other breeds may be affected. Various disorders can disable the secretion of parathyroid hormone. The parathyroid glands may be damaged or inadvertently removed during thyroid surgery. If adequate tissue remains, however, glands will often regenerate following damage, eliminating the signs. Inflammation of the parathyroid glands, throat cancer, and canine distemper virus can also cause hypoparathyroidism.
Rarely, the parathyroid glands fail to form in some puppies. Affected dogs are restless, nervous, and unable to control muscle movements. They may appear weak and have intermittent tremors that become convulsions. Longterm hypoparathyroidism can also cause abnormal hardening of certain parts of the body such as ligaments , decreased mental function, cataracts, and reduction in bone volume.
Blood tests may show lowered calcium levels and higher than normal phosphorus levels. How well an animal responds to treatment may affect the diagnosis. The prolonged contraction of muscles should be treated initially by restoring blood calcium levels to near normal. A veterinarian can accomplish this by giving calcium gluconate through the vein. Longterm maintenance of blood calcium levels is necessary if parathyroid hormone secretion is impaired.
This can be attempted with a diet high in calcium, low in phosphorus, and supplemented with calcium and vitamin D 3. Your veterinarian will be able to advise you as to the appropriate treatment options. Also see professional content regarding disorders associated with calcium, phosphorus, and Vitamin D.
