Customer Question

my dog has an open boil on its back. I squeezed out the blood and puss and put an antibiotic ointment on it. What would have caused this? How do I treat it?

Hi Annette,

Have a few questions,

Did this infection have as hole in it before you squeezed, or was it like a big pimple.

If it had a hole in it, what state do you live in?

I'll be waiting

That sounds like a regular abscess, and you did pretty well.

I asked about your residence, and a hole before you popped the thing... There is a condition where certain flies will lay an egg on a little sore, not maqggots, now, but a warble. One big maggot-like larva will develop in there, with a 'peep hole' and two black spots looking like eyes looking out. Eventually the warble leaves, and these spots will fester. The hole is about a quarter inch around, and the swelling may be the size of a nickle, or more.

The skin around these is thickened. Looks like a gopher hole, only lots smaller. The warbles cause a reaction in the tissue, and sometimes these are slow to heal.

An abscess has a pretty thin covering over it, when it pops as easily as you described, so we may be looking at a warble after all... An abscess can start from almost anything.. dog can run into a thorn, or a splinter, or whatever. Also, an abscess doesn't tend to be deep, like the other thing. That one may be half inch deep,if you count the swollen sides.

Oh well, treatment is essentially the same.

I am going to assume your dog will let you do pretty much to him without leaving, so.. get some peroxide and Q-tips.

Let me post this before I lose my internet connection. I'll finish in ther next post..

I'm new too. I can spell, just have trouble with typing.
You did fine...I messed up by not requesting information in my first reply. Couple of beginners.

Pour the peroxide on the areas. Don't be stingy. It won't burn, but may 'itch'. If there is a hole, try to swab it with the Q-tip. Some betadine (available at the drug, or WalMart pharmacy)into either wound next. Check it daily and put some ointment in it every couple days, then let it dry. There shoul;dn't be any drainage, but if there is you can get after it with the peroxide.

The swollen area is about the size of a quarter. We live in North Dakota. Not too many flies this time of year? I will get some peroxide. She is a good dog and lets me do anything to her.
Customer: replied 8 years ago.
This is/was about a half inch deep and still has some pretty good mass to it.
Customer: replied 8 years ago.
She is on 2.5 mg of Prednisolone to treat an auto immune disease. She is still bleeding some from the hole. Is this because of the Prednisolone?
Customer: replied 8 years ago.
She is settled and the ozing is almost completely stopped. I am going to bed and will check to see if you gave more info in the morning. Thank you so much.
Expert:  Peter Bennett, DVM replied 8 years ago.
I doubt the pred contributed to the bleeding. It may have lowered her resistance to where she got more of an infection than she should have.

If you have any doggy antibiotics in her kit, like an amoxicillin, or keflex, or cipro, you might give her some for a couple days.

This got sort of out of phase when I sent you the wrong form...How long had this been going on, and was she reacting in any way? What breed, and the autoimmune condition?. You can use the PM feature.
You set a good example...Bedtime for me too..
