Working on a new dog

Working on wife to agree to a new dog. I am thinking an English Mastiff hoping while still a big dog there is less slobber than my Neopolitan Mastiff who is in dog heaven (sadly).

Wife is thinking snoodle dog. Less fur and no slobber.

I am thinking two dogs.

I am texting puppy pictures to wife.

I am seeing my 13 year old Mastiff mix is getting slow and how much longer will she be around. So a second dog would help (me) if I lost my Mastiff mix.
