My dog acts strange, walks in circles, is aggressive. Should I worry?

I'm sorry to hear that you're having this problem! If this has been a fairly sudden behavior change for Elsa, the first thing I would suggest would be to have her examined by a vet to see if there may be a medial reason for the aggression - many illnesses including thyroid problems and neurologic issues can cause sudden mood swings and behavior changes like this, as well as anything that may be painful such as an injury of some kind, arthritis, etc. If your vet determines that Elsa is healthy, then I would strongly recommend making an appointment with a veterinary behaviorist as the next step. Aggression towards humans is a serious and complex behavior issue that needs to be handled by a professional who can work with your dog in person. The behaviorist will evaluate your dog and help you determine what is triggering the aggression, then put together a detailed training plan to work on the problem. You can search for a board-certified veterinary behaviorist in your area here: www.dacvb.org

Hello. Is the circling always in the same direction? Can you call her from the circling & stop the behavior? If not, this may be indicative of an inner ear infection, or more seriously, a brain lesion. You should have Snickers evaluated at your earliest convenience to diagnose the cause of this behavior. Once done, then the appropriate treatment can be initiated to help her to heal. Best to a speedy recovery & thanks for using Petco Pet Education Center, formerly Petcoach.

Poor Ariel! A sudden change in behavior could be due to a medical illness; for example, if she is having accidents all over the house, that could be due to a UTI or bladder stones. I would take her into the vet in the morning. The vet can do a physical exam, routine blood tests, and a urinalysis to see if there is a medical cause behind her sudden change in behavior. If a cause is found, the vet can prescribe an appropriate treatment for it.

Hello, I'm sorry to hear that Luna is having this issue. I suggest you get her to a vet as soon as possible for an exam and treatment. This sounds very serious. I don't know exactly what is going on with her but it sounds neurological - maybe a form of epilepsy or a brain lesion. Could also be due to a toxicity or a problem with her eyes. I strongly suggest you get her an exam as sion as you can.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bundy! I am very worried about a sudden behavior changed and circling in an older dog. I am concerned about a central nervous system (brain) problem like a stroke, brain tumor, dementia/cognitive dysfunction, sudden blindness, or vestibular disease. I highly recommend an exam by your Vet. I wish you and Bundy the very best!

First thing you need to do is to get Yoko to your vet for an exam. Often times when older dogs have a significant behavior change it is due to an underlying medical condition. So, you need to rule that out first. She could be having vision or hearing issues. She may be in pain somewhere (arthritis). If nothing is found by the vet then you really need to seek the help of a professional IN-HOME dog trainer. Hope this helps.

Any dog that all of a sudden acts aggressive it is usually due to some type of pain in the body. If he is not eating he may have an intestinal obstruction and that is painful. I suggest you get him to a vet for an exam.
