they are delinatly cheaper!

i would try and avoid places like the RSPCA though coz u never kno wat ur gettin and its risky wiv a baby on the way. we hav had problems lke that before, got my dad a dog from them, ment to be good wiv kids, bit my little bro, then they got another, collie cross lab, grew into a BIG aggressive dobie/rottie type!
they not all bad though.

but if u kno wat u want, stick wiv breed rescue places.
