Have you changed foods?
Has she been vaccinated?
Has she had a fecal run?
Did she come from a kennel or pet shop?
What is her gum color?
At this point in time I would have the puppy in for Fecal check. This will rule out the major reason we see in blood in the stools of puppies, which are parasites which include Giardia, Coccidia, Hookworms and other parasites. Puppies can also eat some no-no's which can cause intesinal distress and blood in the stool. The last problem may be colitis from the change in diet. All these problems can be ruled out with a fecal examination by a Vet. If you have not had the puppy in as of yet, I suggest a vet visit with a stool sample to be examined. Joan
I did want to add if the stools get loose or she starts vomiting, you will want to have her checked for Parvo Virus. Since you did not mention diarrhea or vomiting I hate to be an alarmist, but the blood in the stools, diarrhea and Vomiting can all be symtoms of Parvo. The fecal sample can reveal what may be happening. Joan
I hate to mention Parvo, but I did not want to leave that out should the symptoms intensify. As you said this may be from the change in food or a parasite issue which is common in young puppies.You can try a bland diet to see if it may help. Use boiled boneless chicken breast 1 part to 3 parts white rice. This will allow the stomach to rest. I am not worrying about payment. My first interest is in making sure your puppy gets the best care and you have the best information. I wish you the Best in the New Year! Joan
