Thanks, pixie. Unfortunately our little terrier was set-upon by 4 dogs (our was on a lead) a few years ago and he now attacks all male dogs on sight, unless restrained. All his friends are 'girls' - he'll happily accept 'Charlie' (Sprocker) as a holiday companion and also my other daughter's greyhound girl, who is due to arrive chez nous in August -legs everywhere for a while! :)
