Yes, they are expensive, but they are a hospital. You are paying to be seen immediately and they have expensive medical equipment on hand that most vets don't have. If I'm sick and go to a hospital I know it's going to cost more than my primary care physician for the same reason.
I have fear aggressive American Bulldog, I usually have to keep my dog muzzled and most vets and techs stay as far away from my dog as possible and make me feel like she's a bad dog. Every time I've been to Blue Pearl they have always treated my dog so well and never acted or treated her like she was bad. They understand she is scared and are calm and patient and act like they really care about her.
