My dog is limping and has a shoulder lump. Is the lump causing it?

Pet's info: Dog | American Pit Bull Terrier | Female | spayed | 70 lbs

Hazel was shot in her shoulder about 2 years ago, and got treated for it. She had surgery. Yesterday I noticed she was limping, so I felt around her paw and everything seemed fine until I seen her shoulder, it has a huge lump over it. Is the lump affecting her walking? She's not crying either.

Hello, and thank you for using Petco Pet Education Center, formerly Petcoach. Since Hazel's shooting accident was so long ago, I wouldn't expect her current limp to be directly related to that injury. I suspect this is something new. It's difficult to say if the lump is the cause of her limping, but it's certainly possible. The lump could be related to an abscess (infection) secondary to a wound, or could be either a benign or malignant growth. It would be best to have Hazel seen by a veterinarian to determine the cause of her limp and the source of that lump on her shoulder. If it's an infection, she will need to go on antibiotics and the lump may need to be drained. If it's a cancerous growth, your vet can discuss the procedure and cost associated with having it removed. Regardless, this is not likely to be a problem that will resolve on its own so it's best to have Hazel seen by a vet. Hope this helps.
