My mum, out of the blue, has just announced she wants a pug.
The set up is this - she retired 6 months ago. Myself and my 4 year old boy live with her and two cats. Myself and my boy will likely move out in the next couple of years.
The flat is large and spacious, with a medium sized back yard.
Just hoped someone with pug experience would come along and chat with me about it, I am really excited at the prospect of mum getting a pug but just wonder about the cats and my boy. Will they all get along??

She says she wants to buy from a breeder, but they are very expensive. I think she should consider rescuing one but she doesn't seem keen for some reason. Maybe she thinks they will have behavioural problems. Is this a 'thing'?
Also about training, I read pugs are hard to train, is this true?
Is there anything else she should consider?
Any advice or thoughts would be great, thanks
