My mom's old dog
, Casey, is suddenly demonstrating no appetite.This is a dog
who never misses a meal. She has been throwing up foam, at times it appears to have some pink in it. She is not pooping as much as usual, and the one time she did, there seemed to be a lot of yellow grass like hay in her feces. The vomit also has some of the hay like grass in it.
She is 15, does not see well. She is overweight, but much less that she was when she and my Mom came to live with us....
