But the two are not mutually exclusive

For instance, Dexter was really hard work for the first six months and there were a number of problems; I learned a hell of a lot about dogs in the process and there is no doubt that life WAS more stressful because I'd adopted a dog with 'issues'.

But - one year on and he absolutely brings joy and happiness to everyone he meets. He makes children beam and giggle, and I've seen him raise a smile from some folk who before seeing him seemed very miserable.

He makes me and my family laugh on a daily basis.

So while I understand what you're saying, the two options you present are not mutually exclusive

a friend got a pup from a rescue. But it might be difficult if you do not like staff mixes!

That is my view also and I guess I said that because I have my cousin and uncle visiting and one of our dogs is terrified and keeps barking at them. So although I am confident we will turn him around in time, in the process the neighbours are irritated, my guests can not help but feel less welcome and we feel stressed. So was rescuing that dog for the greater good? I am sure everyone but me think no!
