Would you buy a JRT that was 'bum high' at 8 months? Questions

Hi there! Rather urgent... Would you buy this dog...?

I've been offered an 8 month old male Jack Russell (short legged). I met him today and need some advice to help me make a decision in about 10 hours!

I'd like advice from those with more puppy experience. The main issue I have is his back legs were significantly longer than his front so from the side his bum is about 1.5inches higher than his withers. In horses this is called 'bum high' and they almost always grow out of it but does it work like this with a JRT of this age?

The owners can't keep him due to change in work. He's clearly very loved but quite nervous (not a good thing but I can work with that). They said he was from a puppy farm. He's also quite 'weedy', rather long backed and narrow in the chest and I suppose I'm worried he's got conformation issues that will cause me and him pain and heartache later on. Don't know what to do.

What is everyone's opinion? We're your puppies bum high at 8 months and grew out of it?

Also Is it normal for a young JRT to be a bit weedy? I know lots of mature ones and they're all pretty stocky.

Thanks for your help!

I know nothing about Jack Russell's I would take him to a vet before I agreed to anything.

He's already fully grown. Jack Russells mature quickly. He's badly bred and the clues are all there, he's weedy, he's from a puppy farm etc etc. Take him, don't take him, the choice is yours. I wouldn't pay for him though as you're doing them a favour.
I have a second hand so called jrt cross, I don't think he is but still, he's badly constructed, his legs are too short, his back is too long, his bottom jaw protrudes but he's a great little dog, full of fun, runs like the clappers, never gets tired and is as healthy as can be. I think he's currently around 8 years old, never been ill and everyone who meets him wants him, so it ain't all about looks and perfection.

Agree with trouble. You either take him if don't, he will already be fully grown , he's badly constructed, which a lot of JRT are, construction is usually the last thing on the breeders mind.

His construction may or may not affect him in later life, but then we can't predict the future or what it holds, so my thoughts would be, if you want him take , you can build him up and as long as you are happy you can deal with his temperament then go for it.

I got 6 JRT's personally I would stay well clear of the 8 month one

Thanks so much everyone, all really helpful. With a heavy heart I decided not to take him. It's just too risky, and really I need a confident dog who can go beside me all day with my horses. Plus the owners wanted more money than I felt I should pay (£150). Let's hope he finds a good home.

I think they should place him in a nice home or change a small rehoming fee that seems more reasonable.

I don't know about JRT but most Pits grow out of this. Had a few go through it.
