I have a five year old Border Terrier bitch. She started having what looks like epileptic fits about 3 months ago. The vets tested her and could not confirm this. I have been looking on the internet and was astounded at the amount of Border Terriers this effects. There is research going on in germany and canada into this problem but it seems it is a problem that effects Border Terriers. I am also amazed that every vet I have spoken to is not aware at all of this condition. The dog remains conscious which excludes epilepsy.
It is horrible to see. The dog goes into spasm down the length of her body. This is caused by extreme cramping of the muscles including cramping of the bowel. The distinctive signs are the dog stretching their back legs out behind them and crooking their tail. The muscles along the back come up also. The dog is aware of what is going on but has no muscle control to do anything. With my dog it can last from 5 to 20 mins then she is absolutely fine again.
This is a quote from one of the research web pages..
"Canine Epileptoid Cramping Syndrome ( CECS or formerly known as "Spike's Disease" ) is a recently recognized canine health problem and hereditary canine disease in Border Terriers. It may previously have been confused with canine epilepsy. It is also being considered to be a metabolic, neurological or muscle disorder."
It is controlled by diet and the dogs can become symptom free. If your dog is experiencing these symptoms please mention this disorder to your vet there has got to be more awareness!!!!!.... I also have loads of sites you can look at that are very helpfull PM me if needed...
