Geeze, Dina~ I'm so sorry you had to live thru that! It's stressful enough on you and the doggies having to go to the vet's to begin with, much less finally getting there with all yours and then being insulted for your trouble

. I'd be so mad, I don't know what I'd do! It's hard to believe they're still in business and I'd make sure that I gave them VERY BAD P.R. at any chance.
I'd hate it too, if the place was stinky when they first opened. The first grooming shop I took Max to (on recommendation of his breeder) smelled like that and I was the first person there; I never went back, even though they did a nice job. The place I go now is always super-busy and it NEVER smells bad. A vet's shouldn't be any different than a doctor's office IMO. And the thing about the thermometer is DISGUSTING... how can they even look you in the eye after doing something like that? You'd think they'd have enough sense to be embarrassed at least. How totally unprofessional and I'd report them to to whoever is appropriate. What if one of your dogs had some weird flesh eating bacteria or something (doubtful, but it COULD be a lot of things) and just b/c your dogs all live together doesn't necessarily mean that they already have what the others have. And besides, it's not sanitary regardless if it's a human or animal! UGH!
You did absolutely nothing wrong and you have every right to be angry. You'd think that someone with 4 dogs would warrant a little more respect than what they gave you, since you obviously have SOME knowledge about your own dogs and dogs in general AND 4 dogs worth of business is A LOT.
I hope you find a vet you really like and feel comfortable with; I like mine ok, but she's one of those that doesn't really listen to you much and when I question her about some things, she tries to make you feel like you are ignorant and she knows all the latest stuff (she can't even type notes on her latptop properly

). Good luck, sweetie~
