For the one's that say they'd keep it in their yard, what about if, like many terrierlads, you only have space for 2 or 3 dogs? Surely if your keeping one or two dogs that are shite but you can't part with them for sentimental reasons then you're defeating the object of keeping dogs for the job you want. Personally I wouldn't like to think i was keeping three dogs but only using one, a good saying I've heard is 'it cost's the same to feed a bad 'un as it does a good 'un'.
