My vet did not want to hear it and made me pay for the meds to treat my other dogs.
My parents adopted an OLD Mini Schnauzer a few years ago and when he needed something done with his ears once, he came home with KC. I was torqued, because it was so hard on him to have it, not like a younger pup or younger adult dog having it!
I understand that it's a "kennel situation" but STILL it's kind of ironic you bring your dog to the vet to "get healthy" and they come home sicker!
BTW, you probably all know it but you can use children's Robitussin for the symptoms!
I also purchased some "fish flex" which is cephalexin for aquariums but the same dosage you can get at the vet or doctor. You just give it 2x a day for 10 days!
The only true wisdom is in knowing you know nothing.
