That sounds a lot like my sister She got a puppy (IN an apartment, top floor ) then they had to give it back cause it was seizures..thens he got a kitten who she had for a while, then got sick and went to the hospital for a long while and her bf and kids moved in with his mom while this happened cause hes an idiot and cant care for his own kids..and LEFT the kitten..so we took care of her. Then a month or so later gave it to the HS cause they couldn't afford to spay it Its sickning I know..I wish ppl would seriously think about it before getting animals..its not just something you 'have' like an object which some ppl seem to think..hopefully it works out for your sis's dogs and she STOPS getting animals till they're ready, if ever that happens
