My dog is pooping blood since yesterday. But my dog is acting normal like a regular dog, wagging its tail and barking. But I am too scared for my dog. I have also taken appointment with vet for tomorrow. The vet told me not to worry in the meanwhile. But I am freaking scared. What does it mean if the dog is pooping blood? Is it because of some internal cut or heat which is quite high these days? Can someone help? Thanks.
