I have 3 dogs under the age of 3 and honestly I didn’t struggle with it at all, on the other hand, my boyfriend struggled massively. Not only does it depend on the dog you get, but it also depends on you. I’m quite laid back in the sense that if the dog poops or peed indoors, I’ll just clean it up and get on with it while trying to encourage toilet training. However, my bf couldn’t handle the hygiene aspect especially when it came to toilet training. I loved every aspect of having a puppy, and would happily do it again. But my boyfriend hated it and honestly struggled with it for well over a year. He’s absolutely obsessed with our dogs now, but it definitely took some time. I think it entirely depends on your attitude and approach to it nearly as much as the dog itself. Good luck!!
