My dalmatian has had several visits to the vets and several courses of antibiotics for what they think is a skin allergy or a bacterial infection. She has had skin scrapes which revealed nothing.
The antibiotics worked if she was on them for 3-4 weeks at a time.
i have Epi-soothe shampoo to use on her once weekly.
This sort of rash has appeared 3 times so far. This time she hasn't had it for approx 2 months and now it has come back.
I've changed her food, she is on burns and has an evening primrose capsule every day. (Has been for approx 2 months)
At the minute its looking like weeping eczema, this has only appeared in the last 2 days.
In my opinion I think it's the way she goes tearing through the bushes in the park when she's out, she's like a dog possessed, always getting minor cuts and scrapes.
Its always on her back end, underneath, where she has the littlest fur.
It doesn't bother her, i.e. scratching or biting.
Its loooking pretty red at the moment but I don't really want to take her to the vets unless I really need to as the antibiotics made her quiet and knocked her off her food a bit.
Has anyone had a similar rash on their dog and treated it sucessfully with herbal/natural remedies?
I was thinking of maybe spraying the area daily with a tea tree solution.

In stead of concentrating on what to put ON your dog to ease the symptoms, why not try having getting her allergy tested.  Speak to your vet re having a blood test and sending it off to Yorktest; this test, although not cheap, will reveal any food intolerances and so enable you to remove the allergen from the diet and hence the problem.  It works out cheaper than repeated visits to the vets, creams, jabs etc etc etc.

Also some conditions such a furunculitis etc need a long treatment with specific antibiotics and so until and unless you get a specific diagnosis the vet is using merely a scattergun approach instead of one aimed at a particular problem.
