Elaine Glen Cove, New York 6/23/2015 5:54:46 AM Our old Min Pin use to do this occasionally. Now our new one did the same exact thing.(Our new one is NOT a puppy, he is 8.) I'm thinking it's a trait among them. This morning he was trying to stand up. Front legs were fine. Back legs were splayed out and although he was trying to stand up, his back legs would not move. But his front legs remained strong the whole time. I picked him up and just held him and reassured him. I thought he was going into an asthma attack (another trait I believe this breed carries...) as he was having a hard time catching his breath, but it subsided. Several minutes later he was able to stand on his own, although wobbly... He proceeded to get up and vomit whatever he had eaten this morning. After that, he was back to normal...but a bit weak.
