With this said, these dogs don’t have to be aggressive – it’s usually a fault in handling the dog or training that leads to this type of problem. Oddly enough, the Jack Russell Terrier tops the list of the most aggressive dogs as well as the breeds most likely to attack people. As such, it’s a good idea to look at both parents to determine how big the crossbreed might get. There aren’t really many breeds that end up crossing with Jack Russells to make true giants, but breeding them with dogs like Pit Bull Terriers can result in dogs that are much bigger than you might expect. While some of the crossbreeds can be tiny, especially if the other parent is a chihuahua or a Papillion, there are also some crosses that definitely get up to at least medium size. This one really depends on the dog with which Jack Russell gets crossbred. How big does a Jack Russell terrier mix get?

While it’s always good to think about the mix of personalities before you are looking at the various crossbreed out there, the truth is that Jack Russells make such a good dog template that virtually anything that gets crossbred with this type of dog is going to end up taking on many of the most positive personality traits of the Jack Russell Terrier breed while also picking up fantastic traits from its other parent. From tiny Papillions to Pit Bulls, there is a Jack Russel cross for just about anyone. Jack Russells can be mixed with virtually anything.

In other cases, though, the Jack Russell side stands out quite clearly and provides dog owners with an energetic and friendly crossbreed that takes on all of the best aspects of both of its parents. There are some mixes in which the Jack Russell side virtually disappears, leaving behind only some key personality traits and some breed-specific behaviors. Jack Russell mixes can be fantastic dogs, especially if you train them correctly.
