How very very sad.
I remember the bunnies too, has anything improved with them?

Smelly ears are usually a infection and cleared up easily with antibiotics, I don't think Dals are prone to ear infections so getting it cleared up once should have fixed it. It's sad that a vet would put down a animal with basically nothing wrong with it. We can hope they didn't put it to sleep and found it a new home.

I agree with calling AC. But won't your mom not let you or something?
