I would be worried that she has a health problem. At 10 years old she may be starting to go deaf, or staring to develop old-age cataracts, or arthritis. Any of these may be affecting her behaviour. Usually siberian huskies remain fit and active well into old age, and this is what makes me concerned for yours (I have had these dogs for 28 years). Get her checked over by a vet. If her problem can be sorted she will be happy for another 3-5 years so it will be money well spent.
