Pet's info: Dog | Chihuahua | Female | spayed | 9 lbs
My senior chihuahua has congestive heart failure and she’s also injested rat poison twice of which she almost died from. Throughout the night, I discovered this morning, that she threw up, has blood in her urine and had soft bowel movement with mucus in it. She’s been coughing a lot despite being on her medication for congestive heart failure. Could the blood be a complication of her heart or poisoning?
