Hey I have a 2 months old purebred staffy and since I have gotten her, she done jet black stools (had her for 1 week today). I'm worried it she is internally bleeding. She was eating dry food and wet food mixed together with the other owner and when I got her we gave her dry food twice a day and she didn't really eat much. Just these last few days I have given her wet food, dry food, and one schmacko strap and she eats most of that. Should I take her to the vet?
