I have an 11 year old miniature schnauzer, and around 4-ish years ago she developed skin allergies in her "lower-back" close to the tail, and she wouldn't stop scratching until the point of hurting herself (we assume these uncontrollable and hardcore scratching "spams" where due to the fact that she has a pedigree, and as I understand the purer the dog the more intense the "faults/defects" of the breed are present.
Eventually she lost most if not all of her hair in that area, and thankfully we've been able to control her allergies through:
diet changing (food and water);
baths with distilled water and hypoallergenic soaps;
- dressing her (she has less itching with them on) from time to time, but not all the time (humidity being a factor for all the bacteria to develop and whatnot);
- allergy medications (when really needed).
She still scratches herself from time to time but the itching is greatly decreased by now, she's finally growing hair again, the issue is that the hair now is much more thicker than her original hair. I was wondering if it has to do with all the lesions she caused herself that the skin got so heavily damaged beyond repair. Or if there's anything we can do about it.
