I have an old (10-12 years old) bichon frisée (sorry for spelling errors, typing on an ipad). When I fill up the whole bowl of food and water, she eats/ drinks all of it, and then she goes and pukes up all the undigested food and water. She hasn't done this before, but started these past weeks. Please help! I don't want her to do get hurt. Please give me tips to help her, and maybe tell me what's happening, please! Thank you:)
Added (1). She goes outside and goes poop, but I don't see any yellow spots in the snow, and she doesn't usually bury her waste.
