Could my dog’s hip dysplasia be the reason why she flips out while petting her?

My dog is about eight years old and has hip dysplasia. Over the past year my dog has had many (about 15-20) agressive outbursts. It only happens when you touch her and it tends to be more to scare us away than to harm. However it is extremely scary and she shows full teeth. When it first started happening we took her to the vet and it turned out she had a bad ear infection. We treated it and for about a month she had zero agressive outbursts. They started again and have continued for about 8 monthes, only when you pet her. We thought it might be because of her hip dysplasia so we only pet her on the had, however the aggressive outbursts continued. Is her aggression due pain from her hip dysplasia (which we treat with medicine) or is it an issue of dominance?

Hi. I am so sorry to hear your pup is hurting with Hip Dysplasia. That is extremely painful and might be the cause of her agression. However, I would call your local vet who is treating her and ask if they can give her something for the agression. They may want to see her or they simply may just give you a prescription medication…and hopefully she will be in a better mood.
Just let them know how she is acting and I am sure they will be happy to give you free advise. Especially since you are already having them treat your pup for her hip.
I hope she is feeling top notch soon. Blessings, Patti
