If you get a pug from a reputable breeder the health issues are minimal. All brachysaphalic (i know i spelled it wrong) dogs have their own health issues, but getting one from a reputable breeder minimizes that risk.
ANY one who says "puggle" is ignorant and you should not listen to them. A "puggle" is a baby echidna not a dog breed. The dog that is being called "puggle" is one of the worst mixes.
