I was doing fine on the death of Roxie when I read in Whole Dog Journal about thyroid problems sometimes causing aggression in dogs. After that article, I cried my heart out. Why didn't my vet ever bring up testing for thyroid. To those out there with a dog that has become aggressive, please check the thyroid levels. I didn't, and now I will never know if Roxie could have been fixed with some medication. She had become more aggressive the past year, and this could have been the explanation. I still have such guilt over putting her to sleep at 3 and one half years old.
