I have 2 male JRTs who i love dearly, they are 4 and 8 and I've had them since small pups. I've just seen the loveliest male jack on a rescue website.
He's an ex-baiting dog and just seems like a sweet trooper, it says he hates walking without other dogs. I think he might like to join the gang.
On the negative side my Dad is very frail and ill and i have to spend a few hours with him daily. Plus it took my eldest dog quite a long time to adjust to not being an only dog any more. I think he'd struggle although the youngest would be delighted.
And, this one is trivial but it's been an awful year with Dad being ill. I have a holiday booked in May and it's a two dog property.
