As long as they are looked after and exercised then I suppose it’s up to folk how many dogs they have. Just don’t go spouting all over social media that you ‘graft’ them every night of the week if you ain’t.
2 runners and a busher do me ok. Busher rarely has a day off injured. My old dogs lamping days are done but he’s still handy daytime bushing and on the hills. Got a 3 year old that’s doing well so that’s enough for me. With work, kids and other hobbies it’s hard to find the time. ?
