Beagles are not good for allergies. They are average shedders. The only way to know if she will be allergic is to spend time with some beagles and watch for a reaction. Some more allergy friendly breeds include the Poodle, Schnauzer, Bichon Frise, Basenji. Labradoodle Yorkie, Airedale Terrier and many, many more. Another suggestion is to get a Beagle/Poodle mix.
