We have an 8 year old retriever x samoyd who other then being a bit overweight is in good health and up to date with immunistations etc. Her diet hasnt changed at all but her poo has - for the past month or so her poo has become really runny and grose. The quantity hasnt changed either, around 2 per day.

Should we be worried and take her to the vet? Or change her diet? (she currently lives on a combination of biscuits and/or those dog meat rolls with the occasional bone thrown in). I dont think I can deal with the poo if this is going to be a permanant thing.
