Our two schnauzers growing up didn't shed at all - as in, I never once had a single dog hair on my clothing! Bisi, however, does shed some. But a big difference between him shedding versus other dogs shedding is that schnauzer hair doesn't seem to 'stick' the way other dog fur does. There is zero on our furniture or on the floor, I only notice a few hairs on shirt if I wear black cotton.
Kelly - I LOVE guinea pigs, but I am deathly allergic to them! My pig who went to college with me was my baby, and I had to take prescription allergy pills in order to have her in the same house. But LucyPig was totally worth it! I am highly allergic to cats, and also find myself mildly allergic to some dogs, specifically dogs with short to medium length 'pokey' hairs, such as pugs and labs. I get hives and itchy eyes, but a Benedryl fixes it quickly thank goodness. I have to be careful not to rub my eyes when I'm teaching training classes, lest I have a reaction. But I have never been at all allergic to any schnauzer or poodle, or other non-shedding breed (which is why the Spanish Water Dog has been a good fit for me).
