Welcome to Just Answer.
Is there any bleeding ?
Basically, Treat this as a regualr wound --
Trim the hair from the area -- then
clean with warm water and soap --- and dry very well
the hair is gone and it is raw
You can then use an antiseptic -- chlorhexidine, betadine, or hydrogen peroxide --
and dry again -
The raw look may indicate that this is a "hot spot" often a allergic primary cause.
what causes it
after cleaning well -- you can apply a small amount of hydrocrotisone. neosporin, and clortrimazole creams -- these are all avaialble at the human pharmacy over the counter. Apply 2-3 times per day .
As to cause -- what breed is your dog?
shepard, chow mix
ok -- this is one factor --- the thick fur can hold moisture within -- and result in an overgrowth of normal bacteria and yeast on the skin. They are common -- the single biggest complication is ifthe dog is licking or biting at the wound. Then an elizabethian collar is necessary.
Can there be internal infection and if yes what do I look for?
You can use benedryl at a dosage of 1 mg per pound every 8 hours. This will assist in inflammation control
I have three others that are going for it and that is when I saw it growing, Light bulb
No -- typically this is a skin infection only -- but a vet exam would confirm that it is just the skin. What do you mean that by "you have three others going for it?" -- that is when I saw it growing -- light bulb?
well thanks this makes me feel better, I will clean it and keep the herd off her. I thought them licking it would help guess not.
I have three other dogs
And the others are licking at it ?
This will cause more of an issue and prevent healing -- so definitely stop any licking by any of them -- then it may satnd a chance of healing. This is a guess from a distance -- but form the description and breed -- this is likely what you are working with.
