Thanks guys i really appreciate all your help and suggestions. I did get Laxapet from the vet which is like a laxative for dogs and cats and the vet said just to keep a close eye on her, but i must say that i can't really see that the Laxapet has helped. She is "going" normally and a few times the poo was a bit darker than normal. I can't understand this as it doesn't look like she is ill though. She plays and runs outside and bites of coarse but only wants to eat a minimum amount of human food. (pumpkin, rice, mash and soft things like that). I think will take her to the vet anyway for a proper check up to see if there is something wrong. Thanks again.
i will let you know what the vet said.
