The vet has made all investigations: of the fecal examination to large blood .... ultimately everything was normal. It was then dismissed with the statement: mei, of ner simple allergy to the tumor, anything is possible.
Well thank you very much!
First, we now have the lining changed about a month ago and what can I say: the dog doing fine;)
His bowel movements is normal. The only thing that makes me suspicious: he was at the beginning of 200 g per day, but he made me each time going for a walk a big pile, which is actually totally uncharacteristic of our dog. Therefore, I have the quantity to 170 g reduced. That does not indeed correspond to the information on the package, but at this information I never could keep me.
I'm just glad it's the dog doing well again. Greetings to all dog owners! :)
