I have a 6-month old Scottie (Brodie) and I believe he has Scottie Cramp. I have had 7 Scotties and have never had this problem before. I would like to hear from anyone who has dealt with this condition.
You can find out if your dog has Scottie cramp by taking him to the vet and having a blood work-up done. If he shows a low level of seretonin, it might indicate this condition. If he was my dog, I would ask the vet about giving him a tiny dose of a Seretonin re-uptake inhibitor, which in humans is used for depression and a couple of other conditions. Good luck with your little dog.
Scottie Cramp is an inherited condition, (autosomal recessive). Dogs afflicted with this condition cannot metabolize seretonin well during exercise, and so their legs cramp up ( flexion) and straighten right out...(hyperflexion). In milder cases the little dog may arch his back and walk with a funny stiff legged gait. When the dog relaxes the symptoms go away. My grandmother bred Scotties as we called them, and I remember her having 2 such dogs.I was horrified at seeing this happen, but she assured me the dogs were not in pain. She would try to keep them quiet, and seperated from the other dogs, as much as possible, and she had them spayed and neutered. The only other info I have about this condition is that the health of the dog is very important, such as very good quality food, strict worming and the proper regimen of immunizations. Keeping them fairly quiet and not letting them get excessively worked up seems to help. I'm sure there are drugs to treat this now. To the Op, I would look at the pedigree of the parents of this dog, and I would definitely not breed him. Good luck with the cute little guy.
