My dog was from a hoarder’s home. I agree that it starts out well and then gets out of hand. She was in a NYC apartment with 125 other dogs! I’m sure the person had mental issues.
My daughter and I have made a pact..... if I get to be a dog hoarder (I have 4 now) or if she gets to be a cat hoarder (she has 4 now) we will intervene on each other.
WE both find it very difficult to pass up an animal that needs a home.
