Yes, there are sometimes very strange encounters in the vet reception area and I often wonder what the owners are thinking. After all, sick dogs go to the vet!!
I usually try to avoid dog to dog greetings in the vet office for that very reason alone--makes perfect sense to me, but apparently not everyone possesses common sense!
My one encounter with someone that left me shaking my head involved a woman there with her children, looking at a dog to adopt from the vet's pet orphanage. I was there there on an emergency nose bleeding situation with our Barkley, about 10 days before he passed away, in the final stages of his hemangiosarcoma diagnosis. I was trying to keep him calm, had the nosebleed under control, but his vet told us to come in right away because she was going to try a cauterization to stem it from restarting. When I got there all six exam rooms were occupied and there was a full waiting area. We were coming in without an appointment, a work-in, so I knew we might need to wait. We got over to the far side of the room, away from the pet orphanage area. I took out a blanket and got him situated. This lady takes the dog (on leash) over to us from the far side of the area, to let him sniff Barkley. Of all dogs in the waiting area, she picked Barkley???
I told her he was ill, yet she persisted.
I then physically stood up and announced to her in a voice the reception staff could hear (we were in the blind spot for them so they weren't aware, even though they are usually on top of things), "M'aam, I told you my dog is ILL, he has cancer, is getting chemotherapy, is bleeding and his body fluids are TOXIC (which was technically true, though we were out of the 5 day time frame for toxicity). PLEASE LEAVE US ALONE!". Two of the reception staff people came out and walked her away and then walked us to the hospital area to wait to see the vet. I was steamed! I sure hope they decided not to adopt to that family!
