Okay.. actually it's not even my dog. I brought this homeless dog to my house couple of days ago. She's been around my work place for about a month and nobody seems to care. I felt bad for this dog because she seems to be hungry for affection. I wanted to take care of it for few days however today when I came back from work.... my house was a mess. She peed all over my home. I felt so angry and I've lost my mind for a minute. I kicked her stomach little too hard. She cried out really loud and since then she doesn't move much and I just found out red marks all over her stomach. It's been 2 hours... she's still whining, should I take it to a vet or something? or wait and see more? I don't want to spend any money on her though, especially in this economy. Where can I find a free vet? I mean it's not even my dog.
