She did have allergy shots, weekly. The vet gave up on them this year and she is now only on steroids (and baths). We have been through it all, believe me. I always say if anyone has questions about dog allergies, ask me. I’ve been through 9 years of it in the worst way, as the vets say, trying everything known to man.
I was glad to see your Collie, BTW. I love Collies, too - would like if I could just have a Smooth. They’re my 2nd behind my GS.
There must be an award for love and patience and if there is you will win hands down.
Collies are outstanding furbabies but aren’t they all really? LOL...
