My Sheltie had been very ill last fall and 5lbs. Since then, he has only gained 2lbs. back. While at his annual exam, I mentioned this to the vet. He checked his thyroid level and said it was high. I failed to tell him that Shelties levels should run higher than most breeds. He lowered this medication. After a few weeks, Hunter developed dry skin patches and was getting seizures at least once a day and sometimes twice a day. He also had lost another lb. I took him back to the vet. I took with me printed material about Sheltie thyroid levels and low thyroid can cause seizures. The vet put him back on his usual dose of thyroid med. He is eating better and the dry patches are clearing up. His seizures have are now almost gone. This is one reason that we as Sheltie owners need to know the specific needs of this breed.
