Views on dog hygiene vary a lot. I have one friend, a dog breeder who shows at Crufts etc, who allows her 3 dogs on the furniture and and to sleep in their bed. She also lets, nay encourages, them to lick her face - including her mouth (ugh), she calls it kissing.
This makes me wary of accepting invitations to meals, or even a coffee, at her's.
My last dog just died, but I still have two cats which I love dearly, who all have their own bowls and are not allowed in bedrooms. You can train them to stay out of bedrooms, you should see them run if I catch them on a bed!
You can get useful dog bowls and bottles to keep in the car for pets. Buy her one for Christmas its only 6 months away.
