I think it's awful that people are so judgemental.
One of our friends had a dog. He changed his and his partner's life - they were deliberately child free, but both suffered from depression due to work/menopause. My friend (bloke) got out and went for walks, doted on him, it was absolutely lovely to see. His partner had him in bed with her and it calmed her enough to sleep.
The judgemental, nasty, horrible shots at these people are disgusting. I haven't read the full thread, just the first page and that's all I need to see.
I've got two kids and this couple dote on them. They're brilliant. They also loved their dog. When he died, they were absolutely grief stricken as he was a rescue and already old. Horrible bastards who'd put down that grief.
Oh, and they did take him in a pushchair. He had arthritis and couldn't walk but loved being out. His whole demeanour would change. It made me smile to see it, and every other person in our village - and not in a snide way either. It was lovely.
