Have already taken the 3 yr old YFL to the vets for blood test and am waiting the results. Last week my very active pup comes into the room and it seems like she has something stuck in her throat. She had taken the stance like she was going to vomit. I check her air way and found it to be clear and then she staggered very stiff legged for a little more than a minute and then she was fine back to normal immediatly like it had never happened. We trained last weekend dog worked hard handled pressure fine. Well this am she goes outside like normal and jumps back on the bed and seems unstable like before and this lasted less than a minute. She went to the vet this am and found nothing took blood samples everything else seems normal... We are gone most of the day so she maybe having these episodes more frequently... Any ideas of what I should look for check for? She eats well "dog fuel high in protein" not had a heat cycle this summer and is due in March, is kenneled 12 hours a day and won't pee in her kennel so that is the first things she does when she is let out. I can't think of anything else. But she has me worried now
