I have noticed my girl had sores on the inside of her right hind leg. It is all red and has spots of yellow puss :( she allows me to touch it and expect it without looking like it is causes disstress to her. But should this just need bathing with something or should i take her to the vets. She has been biting madly around her back legs and bum area for 2 days now, but she is fleaded up to date, and so are the cats, and can see no fleas on cats and no fleas on her (she is a white dog so very easy to see them anyway) but gave her a good going over, and no fleas present in the house either, me or my child have no bites and also the cats and dogs dont have bites on them or no flea lavae/poo (whatever the black stuff they leave is).
I think she may be in season, her first one, im not sure as have never had a female dog but she is now 7months old and her 'bits' are stained with somethink dark red, but no blood leaking out as such. Does this sound like a season??? and could this have something to do with the sores or biting??
Also ahe was wormed just under a week ago to which she was sick with in 5 hours, so i thought i would leave worming again for a few days and then go vets and have a worming tab of him (she was fine with this one when she had it before), he sold me the tabs but said to wait another 3 days before giving it to her. Thats today. Could it be something to do with the fact she eeds worming and is long over due ?? and if not is it safe to worm her now after finding this ???

Can anyone help?

I think a trip to the vet would be the best choice, the biting may be due to blocked or full anal glands, the red staining might be an infection, is her vulva swollen ?, if it is she may be in season, but you should really get her checked to be on the safe side.

Could the sores be urine scald? sometimes if the pee sits on the skin, it burns and causes sores, much like nappy rash. The red staining could be from the wee too and where dirt accumulates- we have had both things with Eve - around her vulva and at the base of her belly where her legs meet. Make sure you clean the area , dry it thoroughly and dab on some sudocreme. The soreness makes them bite or scoot or rub their bits. Eve can't reach to clean so we have to do it for her :-D

Are they like acne in humans ? Could be pyroderma easily cured usually by course of anti biotics. Agree trip to vet in order

hi thanks you all for replying. The sores have gone now, but she is left with dried flaky skin in the that area where they were and a bold patch (dont look red or sore though). She also has a small circle of dried skin on the side of her belly, this looks red compared to on the inside of her back leg. She looks quite dirty underneath, i used to bath her every day as where we walk it is very muddy, but was told that that was not neccessary by a vet nurse, should i go back to bathing her more, could it be the dirt causing her to rash and flake?? When i do bath her i dont use a shampoo as last time i did her skin was flaky all over (but didnt look red and no sores) was just told she had sensitive skin and not to use shampoo, been to nervous to try another brand as it took weeks to get rid of the flakyness.

An Oatmeal shampoo can be good, but I would simply put a Barrier moisturiser like Vaseline on any dry or scaly spots and it will soon improve if there is no infection present.

Bathing will strip oils from the coat, but you can easily use one of the Baby Bath liquids in a warm bowl of water and use a cloth or sponge to wipe off the worst of the dirt if it doesn't simply dry and brush out.

Is she spayed or still yet to have a season as a very infantile vulva can be prone to cause urine scalding, a bit of Vaseline rubbed around the are will prevent this.  Worked very well on my kids bottoms, as they were allergic to Zinc And Castor Oil, Sudocrem etc.

she is not spayed and as far as i am aware has not yet had her first season. She has no swollen 'nipples' (sorry about wording my mind went blank and thats all i could think of putting haha) and has stained vulva, dark colour but not leaking blood as such but dont look swollen and have seen no change in personality apart from being more obedient (have been doing alot of training though) and being very greedy recently despite being fed more than enough food for breed and age and weight and exercise. But I have heard sometimes a bitch's first season can go un-noticed so I am looking out for any little signs but none yet. she is little over 7months old. Instead of bathing her i will just wipe over with a warm cloth, dry and rub either some sudocrem or vaseling over said area to help with that and hopefully see an improvement, thanks for advice :)

It's the small vulva and muscular thighs that can cause the staining and urine scalding as the urine isn't thrown clear as when the vulva is more adult.  Immature bitches can also be prone to mild vaginitis (a low grade infection) that often clears up once they have a season.

i used to bath her every day as where we walk it is very muddy

I had a dog once that was allergic to mud and came up in sores underneath during wet rainy seasons if I didn't wash and dry her thoroughly underneath after every wet muddy walk. She would get very sore between her back legs and under her armpits. Has this only happened since she has been getting muddy or did it happen during dry spells as well?

only happened since the wet muddy cold weather :( and she loves to run in the bog, no matter how much i try to avoid it.

I didn't bath my dog all over as that would not have done her skin/coat much good a couple of times a day. I used to just stand her in the bath and shower her underneath with warm water ( only occasionally with shampoo, but usually just warm water) and then dry her well, this was sufficient to stop the allergy and the sores setting in. I'm not saying that this is your dogs problem, but it is worth bearing in mind.
Had she been a small dog I would have invested in a waterproof track suit to keep her undies clean, but I can't imagine a GSD in such a thing !!!!!
