My pit has lost so much weight. Please help!!!!
My pit is almost 8 years old. Recently She's lost all of her weight and is nothing but skin and bones. She doesn't seem to have an appetite and she's been groaning when she lies down and when she poops (never heard her do this). She drinks lots of water and then it's like she gags and spits up almost every time even when she eats. I've tried changing her food, but nothing seems to help. She's breathing heavier and doesn't seem to get comfortable at all no matter how she lies. I'm desperate and need to know what could be wrong. Please, please, please help me!!!!!!!!!!!!
