my dog, a border collie mix, is at least 10 yrs old and has a tumor in her lung. I took her to the vet b/c of her coughing at the time, about 6 mos. ago. She's not coughing much now but now her main problem is the greenish mucous from her nose sometimes. Is there anything that might help that? I'm trying to feed her healthy food.
