would this puppy be a good idea?

[mattsmadmum]

my cousins has two crossbred dogs. jr cross and a rottie x sheepdog-neither are neutured and she caught them mating last month. the mum has a great nature and has been brought up with kids but the jr x who is dad often snaps but has never drawn blood
experienced with dogs and we are looking for a new puppy but were going to get one from the dogs trust which is where are other dogs came from-but not sure if i should have one of these pups due to dads snappy nature as have 4 kids-any advice welcome

I reckon a dog from a shelter would be better because they'll have been assessed and their personalities are known. With a puppy you have no idea what you're getting, plus, puppies are hell. (I say that as a mother of a 5 month old Pointer cross, who I adore with all my heart)
I've never met a jack Russell that isn't a bitey fucker, and you don't know if the puppy would have inherited its fathers horrible traits, or its mothers.
Plus, 4 kids and a dog?! You're brave!

Unfortunately I say the opposite to PP. Buy as a pup. A regimes dog may have a difficult history the home are unaware of and you just do not know.

A puppy, you make from scratch! My rottie is perfect because from day one we trained him to accept he'd be mauled and cuddled to death. He loves DD.

I also never met a jack Russell that wasn't a bity fucker and sheep dogs are crazy. Stay away

I'd be more concerned about these pups' first 8-10 weeks. Sounds like your cousins are a bit feckless (didn't bother to check carefully that their bitch was coming in season and keep the dogs separate, then didn't bother getting the bitch the "morning after" injection when she was covered). So I can't imagine them carefully handling each pup every day, getting them used to children in a controlled way, starting to gently discourage overly vigorous play biting, handling their ears, mouths, feet tails etc. You can start this when you get the pup, but you'd be better off getting one that has had a good start, or getting an older one whose character is more formed and who is proven to be gentle as EvenBetter said.
If you decide not to take one of these pups, then stand firm even when they're trying to press a 16 week old into your hands when they've failed to shift them all on gumtree.

thanks i think everyone is right just needed someone to tell me i am being a fool. So its back to the dogs trust

Can I just say ,in defence of JRTs , that my mum has 2 JRT x border terriers and the boy one is not remotely snappy ,he would lick you to death .
