Pet's info: Dog | Staffordshire Bull Terrier | Female | spayed | 25 lbs
So, i sent pictures of a lump that had developed on my dog overnight the other day. She already had a small pink lump in that are which shes had for years but fluid developed behind it. Yesterday the fluid had mostly gone, but today the are is inflated again, but its more firm. Any ideas what is causing this? And if this is to be serious, would my dogs behaviour change? As she has been the same happy dog she always is. She is 12 years old by the way.
