Most allergy sufferers are actually reacting to pet dander rather than hair. If you keep your Aussiedoodle brushed and clean, give regular baths, etc. that usually helps tremendously.
Aussiedoodles are a breed that needs regular grooming to keep them mat free so potential Aussiedoodle owners should plan to groom their pup on a weekly basis. This also provides good bonding time and gives you a chance to look for any skin or coat issues your pup may have.
I like to use a good pin brush to gently brush through my dog's coat. A metal toothed comb is also a good one to have. If you have mats in your dog's coat, you can also use a dematting tool with bladed teeth, which usually does the trick. Just try and be gentle as you work the mats out. You want this to be a good experience for your pup. A good bath with a quality shampoo and coat conditioner prior to removing any mats may also help and may help keep your pups coat tangle free in the future.
