Annette did you really see that? My gosh, I have 5 of those dogs(pugs) and have never heard of that.
As if they aren't big enough pains in the butt they better not start having their eyes popping out of their heads.
It was on a show called "dog 101" on TV. They went through different breeds of dogs and told all sorts of stuff about each breed. When they came to the pug, they did say that. I will never forget it as it was so, so strange to me. They also said they were bred with flat faces and they have great difficulty breathing because of the flat face. They also said they could actually die if they get overheated. Otherwise, they are supposed to be extremely lovable dogs.
I think they said if you squeezed them to hard around their necks or perhaps their head, that's when their eyes would pop out. Anyway do a search and see if you can find this wild, wild information. Hope I didn't upset you.
