Hi there I have recently found this bump on my dog's head, and he also has one on his back. Is this something to be worried about? plus he's also constipated.

It's difficult to tell exactly what is going on on Poe's head based on the picture alone, but I would be suspicious of an adenoma, which are typically benign skin tumors we find on older dogs. They often do not cause any problems and are more of a cosmetic issue. Sometimes we have to do a fine needle aspirate to collect cells from the lump and look at it under the microscope to be able to determine what it is. I am concerned that he is constipated as he is likely very uncomfortable because of that. My other concern is that he could have diarrhea. Constipation and diarrhea can look very similar with the dog straining and not producing any stool. The best thing to do would be to take Poe into your vet for treatment of the constipation (or diarrhea) and have your vet look at the lumps at the same time.
