my pup was 12 mouths old and it ave done here any harm
a pup will go when its good and ready it depends on the dog itself and if you been into terriers long enough you will know whens the right time some are to keen for there own good so need holding back a bit where as others just need that little bit longer its all about knowing that individual dog atb biza
this is my first terrier hes 5 months now and a game wee bugger he is he would go too ground now if i let him
cheers lads
