My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
There can be many reasons for a dog to collapse including vestibular disease, organ failure, and heart issues to name a few. I can give you information on these conditions.
Symptoms include standing with legs spread out, swaying, head tilt, abnormal eye
sideways, falling over and may include vomiting. There are a few things that can cause this condition such as an ear
infection, some medications and old age
. You do indicate that there is no head tilt or abnormal eye movement, so this may not be the issue.
Here are some great sites on this condition:
Liver and Kidney issues can lead to seizure activity and affect your dog's quality of life. At her age, it is possible she is experiencing organ failure.
A dog may also "faint" in which they fall to the ground usually on their side, stare straight ahead and seem paralyzed which indicates a heart problem.. This is called syncopy and can be read about here:
So I do feel you need to capture video of her exhibiting this behavior
and then have your vet do a senior checkup on her. However, she is quite elderly so you may be looking at a situation where euthanasia would be the kindest course of action. We usually evaluate if the dog has any real quality of life. If they don't have any activities they can still enjoy or are in pain all the time, then it is likely time to consider euthanasia.
I hope this information is helpful to you. If you need more information or clarification, please reply and I'll get back to you as soon as possible. If you are satisfied, please take the opportunity to rate.
