TASHA UPDATE

tasha my min pin got a lil better they didnt find anything in her blood tests, she hasnt had diarrhea but she is still underweight and it looks to me like shes getting skinnier and skinnier still....AND today i noticed she was limping and theres something wrong with her front leg, it looks swollen on the joint..im really worried about her now, especially since we cant take her to the vet right away, we're leaving tomorrow to arizona for my cousins wedding and we'll be gone for 4 days. and I know my irresponsible brother isnt going to be taking extra care for her :[[ what could be wrong with her??
