Have you looked for symptoms on the website www.web-dvm.net Good luck. I use this website to find out things I need to know about my dog. Its like webmd just for your pets.
My Dog Looks Like His Front Legs Are Giving Out And That He Is Going To Fall But Then He Catches Himself And Doesn't Fall / /? Like Someone Who Has Nodded Off But Then Awakes As His Head Is Beginning To Fall On His Chest.What Could This Be?
Did you get an answer? My dog does the same, otherwise she's fine. Happens during our daily walks about 3 times within a mile, her right front leg gives out but she just keeps going. Shes a 5 yr old healthy lhasa, not overweight. This has been going on for about a year. Hasn't gotten worse and no symptoms of any pain.
