Does she get a bit of food just before bedtime? Sometimes Yorkies will vomit foam in the morning from an empty stomach.
What kinds of treats was she getting before she became sick?
Small tinges of blood in the poo can come from almost any kind of intestinal upset. including parasites, bacterial overgrowth and others. Dogs can all of a sudden develope allergies to foods or things they've been on or around for years.
Hope she's feeling better soon and your vet finds out what's going on with her.... |
