...hmmm

...this is a little problem

...one of my best friends has the same problem,luckily all my family love dogs and I have two boxer at home but for your mum...you can try to tell her that you want a lot a dog but maybe this way isn't the best...or you can try to make some little favours or some little works for your mother, sometimes it works. And for the cats problem, if you take a dog when he's puppy, he will lives with cats and he will accustom, and an adult dog, you can try to teach him that he never hates cats!!!
