11 week old puppy.
Took him to the vets for 1st injection 2 weeks ago. The morning of injection he had some mucus and blood in his poo. Spoke to the vet and as he came from mother home being fed pedigree and I had introduced a small amount of wainwrights in order to change food (about 4 biscuits) the vet told me to stop and leave it for another couple of weeks before introducing the food. I still have him on pedigree as his stools still seem loose to me.
Today he has had a large amount of runny poo with mucus and blood. He has been wormed and is otherwise well in himself.
I have considered that it could be the pedigree food actually doing this but has anyone got experience?
Vets open in a bit but they did not seem too concerned last time but I am going out of my mind!
