Jessie is a staffy 11 week old female pup, we noticed yesterday she has a weird scabbie looking thing on her lip, it is about 2cm long by 1.5 cm wide, as much as i can tell you is that it is dark in colour but her muzzle is dark as well, and its like a scab, what do i do? she is due for a needle soon do i leave it till then to see the vet or take her asap? please help. My husband said it could be cancer. i hope not.
