This is not just your run of the mill angry dog. Rage Syndrome is a genetic disorder that acts like a seizure in the emotional center of the dogs brain. A dog with this syndrome will go from a sweet and normal dog to attacking, vicious, frothing at the mouth dog with no warning signs. As quickly as the rage comes it disappears. Where an average dog will display signs of irritability and potential attack a dog with Rage Syndrome will simply snap out of nowhere for no reason at all. Many owners that witness their dog experience Rage Syndrome describe a glazed over look in the dogs eyes during and after the attack, almost like the dog is out of body. This can happen in any breed but some breeds are notorious for this syndrome. German Shepherds, Belgian Malinois, Dobermans and Newfoundlands all are known to get this, however Springer Spaniels are the most notorious breed to get this syndrome. It happens often enough to garner the name "Springer Rage." That said, true Rage Syndrome is extremely rare and is genetically transferred so make sure you know the background of your dogs parents before buying.
Fly Snapping Syndrome
This syndrome is thought to be caused by a type of complex partial seizures in the dogs brain, however, the full cause is not known. The seizures are thought to causes the dog to hallucinate, they visually see invisible flies. They will follow them with their eyes and snap at them to try to catch them. Many dogs with this syndrome lick their front limbs often while this is happening. Studies have found that a seizure medication can help to alleviate the syndrome. While the behavior is not particularly dangerous, it is important to get it checked out because a larger seizure could prove life threatening.
White Shaker Syndrome
Almost exactly as it sounds, this syndrome effects small white dogs and causes them to shake. Also known as idiopathicIdiopathic means there is no known cause. steroid responsive shaker syndrome, the disorder has a sudden onset and can be worse in times of stress. The shaking can go from mild to so severe it causes difficulty walking and seizures. The full cause is unknown but it is thought to stem from the immune system. The most commonly effected breeds are the Maltese, West Highland Terrier, White Poodles, and Bichon Frise. The most common treatment is steroids but in severe cases valium can also help reduce stress until the syndrome passes.
Small Dog Syndrome
If people can have a Napoleon Complex, so can dogs! Small dog syndrome is just that. It is where a small dog acts larger than they are. The small dogs will be nasty and snippy and try to engage dogs 10 x their size in fights. Sadly this syndrome stems from the owners behavior. Dogs that are carried about and allowed to misbehave because they are tiny tend to end up with small dog syndrome. If you follow the rule If it's not ok for a big dog it's not ok for a small dog you should have a normal balanced small dog.
Hanging Tongue Syndrome
If your dog can't get its tongue back in its mouth ever then it likely has hanging tongue syndrome. This syndrome is most common in small breeds like Chihuahuas, Cavalier King Charles Spaniels and Chinese Crested, and in brachycephalic breeds like Pugs, Bulldogs and French Bulldogs. Essentially a genetic malformation of the dogs tongue makes it impossible for the dog to put their tongue in their mouth. This can cause drying of the tongue leading to other problems.
This syndrome is caused by damage to the sympathetic nervous system. It affects only one side of the facial muscles and can appear rather frightening. One of the dog's eyes will have a smaller pupil size (miosis), the third eyelid will protrude while the upper eyelid droops, the eye will have a sunken appearance (enophthalmos) and the blood vessels of the affected side of the face will dilate making the area warm to the touch. While it appears frightening, this syndrome will correct itself after the underlying cause, a bite or other injury or inner ear infection is treated. Often vets will prescribe eye drops to assist with the symptoms.
Bald Thigh Syndrome
This is a syndrome that affects the Greyhound. Essentially it is exactly what the name says it is, the dogs thighs go bald. Bald Thigh Syndrome is a form of localized alopecia which is more prevalent in the darker dogs than it is in the lighter ones but can occur in any. The dogs fur on the back of the thighs disappear. For some it comes and goes but for most when the fur is gone its gone and they are left with some bald legs. The specific cause is unknown and the syndrome is not harmful to the dog other than being cold in the winter!
Happy Tail Syndrome
Don't let the name fool you, this is anything but a happy syndrome. Also known as bleeding tail and splitting tail, happy tail syndrome comes from your dog being happy and wagging their tail. As your dog wags its tail and bumps it into things like walls, tables or other hard inanimate objects it injures the tail. The harder the dog bangs it and the more often it gets hit the more damage done to the tail. Hard hitting on the tail can cause cuts, splits and other impact injuries that are painful and difficult to heal because of low blood circulation in the tail. If the tail is unable to heal or the injuries are continuous it could lead to amputation of the tail. Larger breeds are most often affected by this syndrome as they swing their tails harder than smaller breeds.
Cold Water tail
Also known as dead tail, broken tail, broken wag and limber tail, cold water tail is simply a limp tail. A dog with Cold Water Tail will be unable to lift the tail and the tail will hang limp from the base or from three or four inches out. Often seen in hunting dogs after hard workouts, swimming in cold water and heavy hunting, this syndrome can be painful for the dog but is not serious and will self-correct in a few days. The actual cause is unknown but possible causes are nutritional, circulatory or damage or over use of the muscles. It is most often seen in dogs with high set active tails and males are more frequently affected. The breeds notorious for this syndrome are Labrador Retrievers, Pointers, Flatcoat Retrievers, Setters, Beagles and Foxhounds.
Dirty Dog Syndrome
This is a behavioral syndrome where a dog confuses where it is supposed to go to the bathroom. Most dogs will not go potty where they sleep, making crate training very effective in potty training. A dog with Dirty Dog Syndrome confuses this and will potty in the crate almost every time it is put in. Often a dog with this syndrome will hold it outside and wait until they are back in their crate to potty. The cause is unknown but it often occurs when the dog is left too long in the crate and begins to associate the crate with relieving itself. The easiest way to fix this is remove the crate for a period of time until the dog begins to learn to potty where you want it. Once your dog is trained to potty outside you can begin to reintroduce the crate.
