hi there, im pretty sure you dog will love a new play mate and will relish it and be revitalised by it all. The person who bought my first bichon had a bichon/shitzu cross who is six. The first few days they were finding their feet, the older dog didnt really pay much attention to it, well a few months down the line and the older dog has become inseperable from the younger one, it has become more pup like itself and they get on famously and snuggly up at bed time together. I think dogs in general really benefit from other dog company, so id go for it!!
