I have had 3 yorkies with it and my 10 yeart old pom has a severe one. I lost Gracie at 6 1/2 years to it and my other 2 had a mild one so they lived until they were 13 and that wasn't what they died from. Make sure ypu never use a collar, keep him as calm as you can and the vet can give you some meds. Good luck |
