Hi there, like you we had Wilf who's 3 and toyed for a while with getting another but probably like you did nt want to make a mistake. I did nt think that Wilf would have a problem with introducing another male, but just incase the alpha male thing was an issue decided to get a female. So we now have Mable as well who is 6 months. I spoke to my vet who said if you were having your dogs done then it did nt really matter whta *** you had as in effect they would be asexual . However Mable is probabaly in charge , which I did read that a bitch probably would be, not in a mean way but he'll move if she wants a drink, I ve to stop her taking his food cos he'd let her etc. So in the long run with hind sight I'm not really sure it matters, but like you I did nt want to make a mistake. Other people may have different experiences though ... good luck with your search keep us informed, let us know what you decided.... Once you get a cockapoo you just cant help getting another x
