Hi I wrote a thread yesterday about my growling puppy aged 16 weeks. there has been an extreme about of growling today and Ive noticed for the second day that he has slightly runny poo with blood in. He has this when we first got him and I took him to the vets who said there was nothing wrong, but gave him anti-biotics and chicken&rice for 3 days. He was also growling at that time. It cleared up, but now its back. What is it??? Do I need to go to the vets again and spend another £64 which is what it cost last time. He is on his normal food which was given by the breeder. Im wondering if his growling is connected somehow and he's not feeling on top form.
