I am a JRT owner (see my Monty Dog posts). I hate to sound negative, but as someone who adores this breed, I spend a lot of time trying to talk people OUT of getting them because as cute and appealing to kids as they are; realistically, they really do not work out in alot of familes.
Here are some things to consider :
** How old are your kids? JRTs are not generally good for families with young kids. I'd say under age 10 it's probably not a good idea. They jump and can be nippy unless extremly well trained.
** Be prepared to spend a lot of time and possibly money on training. JRTs require extensive training from early on throughout their lives. They are very smart, but they are also extremely stubborn and most traditional forms of training do noty work on them. They do respond well to clicker training.
** They can not be kept outside. I don't think any dog should be kept outside, personally, but JRTs need to be kept warm. Obviously, if you live in a warmer climate this is not an issue.
** JRTs can jump very high. You will need a high fence in your yard. At least 6 feet, higher if possible. If they can't jump it, which they usually CAN, they'll dig their way under it. Electronic fences may or may not work on a JRT. They are extremly high willed and I have seen them walk right through the electric fences before. They are strong and tie outs are not a good idea for them unless you will be there to keep an eye on them.
** Likewise, chewing deterrents like bitter sprays etc. don't usually deter them. Basically, what Jack wants, Jacks going to do his darndest to get.
** JRTs need a lot of excercise. Not just your typical walk. They need to be able to seriously run loose and burn off some energy. Or they'll get frustrated and bored and become destructive.
** JRTs are HUGE dogs in small dog bodies. They need to have space to run. They need to be trained from the time they are babies who is the boss but they will continue to try and work their way up in the "pack" for a lot of their lives.
** A well bred JRT is a hunting dog. Your cat, other dogs, small pets and birds may not survive having a JRT in the house. It is generally not recommended that JRTs be kept with anything other than another dog and even that can be chancy.
** They like to chew. They can't have flimsy chew toys. This means you are going to have to spend a little more $$ on hard rubber solid toys, as opposed to toys made of fabric, laytex or vinyl. It doesn't sound like much, but it's something to consider.
** JRTs need a lot of attention. They are not content to just sit quietly on the floor and play with their toys while you eat, type, etc. They want to be WITH YOU. For me, this is part of the appeal but for others it gets old, really fast.
** While JRTs can be kept in an apartment (mine is) they really need to have space to run. Our apartment is set up perfectly for this which is why it works for us. We also have a large fenced in yard like I described.
** JRTs are very curious. Expect them to get into you things unless they are kept high up, out of the way. And remember, with a JRT, high up means REALLY high up.
** The JRT I have described here, could be a 6 month old puppy, or it could be a 10 year old adult. They really don't slow down much as they age.
Of course, on the GOOD side, JRTs are very loving, loyal and ridiculously smart.
*** They can be taught a lot of commands and tricks and enjoy learning and interacting with people. The reason you see so many JRTs on tv and in movies is because they learn a lot and they learn very, very fast.
*** They can be taught to be good with kids. Mine is great with the kids we meet however, we do not allow him to play with any of the neighbors kids unless at least one adult is within 10 feet. JRT's can be unpredictable. We do not let children we do now know pet him unless we are hold him or standing within a foot of him, holding his leash. BUT I should say, Monty seems to know kids. When a kid is petting him, he goes limp and just lets them pet him or gives them kisses. We just do not want to take any chances. Monty has helped at least 6 children get over their fear of dogs.
*** For us, Monty comes everywhere with us. This is something we've done since he was 2 1/2 months old and part of the reason why he is so good with people. He's been used to being in different situations and handled by many different people from a very early age.
*** JRTs are very healthy as a breed. Very few serious medical issues that they are prone to.
I would not trade Monty in for any other dog. He's the best dog I've ever had. But that said, I don't have kids and if I had had kids when I was looking into breeds, I definately would not have gotten a JRT.
Good luck and feel free to PM me if you need any more info.
