puppy....lump on back

I have a 17 week old pitbull. He had his last shots about 2 weeks ago so he is up to date until a year now.

He has been scratching behind his shoulder for a while know and i finally found a lump where he's been scratching.

I've also noticed that he has been urinating everywhere and he can't get enough water. The flow of urine is constant but he can "pee" about 3 or 4 times in a half an hour, sometimes even while he's walking. He normally goes to the door but it seems like he can't hold it now.

He sleeps all night long(7 or 8 hrs) and doesn't have any problems. I would like some advice please about these problems.




Hi Casey
The lump your pup is scratching at is probably residual irritation from having his vaccinations. Many puppies have a 'knot' or lump at the site of the needle itself, and it can stay there for several weeks, even months sometimes. If he seems to be really irritated by this though, you could try some Benadryl (check with your vet first to get the correct dosage for your pups weight), it may help to damp down the reaction.

As for the urination, that doesn't sound as though it's related, although as I'm not a veterinarian, that is only a personal opinion.

Frequent urination can be caused by a urinary tract infection, however as he seems to be able to control his urination overnight, that may indicate otherwise.

When an increase in urination is accompanied by increased thirst, it's possible that another condition (such as Diabetes or a kidney problem) is responsible.

I would strongly recommend that you take your pup to the veterinarian for a check up. That way your vet can run some tests if he feels it necessary and get the correct diagnosis. If treatment is needed, the sooner you get it started the better.

Best of luck, hope your pup is doing better soon.
