The furry two: Yes, when invited. Journey's favourite time of the day is cuddling on the couch with me. I don't invite Dance up as often, because she doesn't really cuddle and doesn't really care. Both are polite about the invite. I can't stand it when I'm sitting on the couch and suddenly have a dog in my lap causing me to spill my drink or something. They have to be polite about it or they lose their privilege.
The Dobermans: No. Their hair is prickly and makes me break out in hives, so I don't like it stuck all over the furniture. And, nothing against them cause it isn't their fault, but I find that they smell more 'doggy' than the other two and I don't want my furniture to smell like dogs. And, to top it all off, my couch is far too small for dogs of their size. And they're both rather pushy and would totally ignore the "when invited" rule and just end up making the couch their new bed.
