The pups had their last 6 week visit. One puppy had an upchuck. I think it was due to a yak treat I gave them. Sound ridiculous but I will try them on it tomorrow to see. It only happened once. It can also be from them eating too fast. They didn't have food 90% of the night and ate like they were starving in the morning. Nothing to worry about but we buy treats ahead of time and test them a number of times. Sometimes they react to something they never had and other times not but as the busy adjusts, so does the reaction much like if you changed brands of food without doing it gradually.
The pups had a good time.
