Just for whatever it's worth, I'm gonna pass on this caution from my holistic vet. I don't hang around this topic much, but I don't see that it's redundant. I'm not trying to be accusatory but I thot, for whatever it's worth, it might be advantageous to know about.
My holistic vet is a former groomer -- so she's always looking at the coat not just from a "healthy shine, etc." standpoint but she's looking at the cut too. But when I brought Billy in last week, one of the side effects he's had from all the long term steroids is some skin issues (Billy has IMHA and is gettng off them gradually -- they saved his life but man, the side effects *whew*).
Now yes, they put dogs with skin problems ON steroids .... but after a while it has the reverse effect and because is so immune-suppressed (IMHA again) the coat on his spine is breaking some and I'm having to chase away topical infection all the time.
I mentioned he was actually headed for the groomer next weekend just to generally straighten up his coat (he's an English cocker) and she asked me if I'd heard about the big study done about skin infections and grooming? I said no.
Apparently in many salons it's typical to water down the shampoo a great deal. It's more economical and you don't get a glop of shampoo on that's hard to rinse.
HOWEVER -- apparently there's this huge increase in grooming related skin infections. According to Dr. DiNatale some shampoos have so many organic ingredients that there is actually bacteria present IN the shampoo. And, because we've got this super crop of bacteria out there anyway that are more and more resistant to more and more antibitoics they are seeing this huge rise in really mega nasty skin infections (like pseudomonas and other hard-to-kill bacteria/skin infection).
She warned me to warn Billy's/my favorite groomer, particularly because he's so immune-suppressed anyway, to be ultra careful to sterilize the blades before and after use, and NOT to thin the shampoo before use. Apparently there's this whole process that occurrs -- the particles of hair that stick to the blades but then shed onto the skin during the 'cut' process, then they aren't removed sufficiently by the shampoo, and the newly introduced bacteria then causes mega problems.
Apparently the incidence of dogs getting bad infections AFTER grooming is skyrocketing, and she actually had one walk into her practice just this past week. She said "I had just gotten done reading about this in my vet journal and I thot it was kinda weird and improbable and then blammmm ... in walks one right into my practice the very next week. The dog's skin was full of pseudomonas and it had started just a couple of days after grooming.
Now I know *my* dog is severely immune suppressed and that's not normal, BUT I also know how huge the allergy threads and skin infection threads tend to be, so I just figured I'd pass it on. I don't have a copy of the study to post - wish I did.
