Bladder stone removal surgery

Hello. My dog had urinary stones removed from his bladder 6 days ago and there’s still a bulging mass. Is this normal? I brought him back to the vet and they said to put cold compress but the swelling doesn’t seem to be getting better.  He pees normally, has good energy, has a good appetite, walks around. I don’t know if I should be worried. Should I bring him elsewhere for a second opinion? 

Hello!  First, cards on table and limitations laid out:  I am unable to assess a pet from a photo online and would certainly never assess another vets' patient without their permission; this is currently outside the scope of this forum.  It sounds as though your dog has had a post-op assessment after a cystotomy and the veterinary surgeon who checked the wound found it to be swollen and asked you to apply a cold compress, which I imagine that you have been diligently doing.  You ask whether you need to see another vet - I do not see why, unless the wound is looking worse rather than better or something unexpected has happened with your dog, and even then you would get better results from seeing the first vet, who already knows everything there is to know about the case so far. However, if at ay stage you have questions or are concerned about a would after surgery, contacting your own vet and asking to talk it through with them is always a very good idea.

*wound*   I would add to this, that most vets will be happy to arrange a second opinion for you in an open, direct way should the need arise. As a new grad, I looked very young for my age and as a direct result, if I didn't say what the owner was expecting, they used to question it (luckily I am from Yorkshire in England where people are open about what they think) - and I would send them to see someone in a neighbouring practice.   This is much better for vet-client relations than the client not trusting their vet.
