Yorkshire Terrier
You probably didn’t know but the Yorkshire Terrier is not a suitable breed for a home with young children as they tend not to have a “submissive temperament”. They require a lot of attention and proper training. Did we mention they constantly yap?! Not bark….yap.
Pugs
These little cuties end up on our list, sorry! It is known that pugs are more prone to aggression because they have a need for dominance, if you don’t show that you’re the “alpha” then they will become aggressive and will want to dominate the house how they see fit. Often times they will bark excessively, bite, growl, and chase other animals around. Pug aggression can become a full blown serious problem if you don’t nip it in the bud.
