Woolsy is changing his fur at least once a year. Is this normal and do all dogs shed their fur regularly? Is there any illness that has a symptom of fur shedding?
I think that shedding is a normal thing but the frequency and the amount of hair would depend on the breed type and overall health of the dog. I have gotten used to brushing my dog's coat from time-to-time, so as to remove the excess and loose fur.
