I'm fostering a lovely 2 year old shitzhu until April when she will go back to her owners. She's a poppet but not really housetrained - she lived in a flat before us and used puppy pads as she was alone 9-5 - but I think we're getting there slowly. I've changed her food to a raw meat diet as she was on Caesar before which I felt was giving her a runny tummy and that has improved things greatly. She's brilliant with the children (2 and 6) but she has started biting me and dh when we move her off the sofa. I wouldn't normally allow a dog on the sofa but I think she was allowed at her 'real' home and I didn't want to stress her...anyway, I need this biting to stop before one of the kids gets bitten. Please advise me!
