Don't bother doing an internet search if your dog is bleeding or you notice blood in its house; get your dog to the vet now even if your dog appears to be o.k.
- Causes of bleeding could include the following:
- The dog is a female that has not been spayed (and is in heat)
- Your dog has a urinary tract infection; if it's bleeding, then it is more serious and needs to see a vet now - not two days from now as your dog could be dead by then.
- The dog has a cut or wound that is not immediately recognizable (look for skin that appears to be a 'flap': the dog has somehow sliced itself - perhaps on a fence or piece of wood.
- If it's winter, check your dog's footpads and between its toes for cracks due to dryness or salt/ice-melt chemicals. (Clean the pads, and be sure to moisturize with Bag Balm or Musher's Secret - both available at your local pet store and online.)
- Ingestion of harmful chemicals or materials.
Note: If your cat is bleeding, there is a good chance it has a urinary tract infection. These are even more lethal in cats, and you need to get the cat to a vet - now, or the cat could be dead tomorrow morning. If your cat appears to be dragging or 'wiping' its rear end across the floor, chances are good that it has a urinary tract infection that has not yet gotten to the bleeding stage. (I note this from personal experience with two of my cats in the 1990s.)
Note: If your dog appears to be dragging or 'wiping' its rear end or butt across the floor and/or has bloody stool, there is a good chance that your dog might have worms or a severe intestinal problem. Get your dog to the vet, quick! (Info/post revision thanks to Colby, whom left a comment on this post.)
detroit dog's advice: If your pet is bleeding and you don't know why, get your pet to the vet now; ask questions later.
