So last night I took in 3 border collies, and a young auss/BC mix. The puppy seems to be sick, owner had treated him at home for what she believed to be giardia? And it seems he still has it now. I have talked to owner over phone and she has given the clear to take him to vet. What concerns me is the dog is heartworm positive, and the treatment would be a dewormer that would interfere with heartworm issues. Yet the vet still wants to go with the treatment? Im waiting for another vets opinion, who can't see dog until Monday morning. The dog is resting in his soft crate. Clean water, food, a little bit of attention in the day. No extreme exercise. I do not want to be having a dog being treated for heartworm in my care. And honestly if this all could wait until Wednesday when owner comes to pick dogs up. I am up the creek with this one. Should I be brining the rest of her dogs in for a vet check also? I am keeping all other dogs away from the Connor boys (the border collies that came with the sick aussie mix) and all places they have eliminated have been off property as of this morning.
