We tend to give Molo 'natural' treats; pigs ears, dried lung, rawhide and bones.
However, a couple of days ago, I gave him a processed treat stick one morning - one of the ones designed to clean the teeth.
I was horrifed by Molo's reaction - he was totally hyper all day; he was nipping, hurtling around, leaping everywhere and reminded me of a toddler on E numbers
If anyone is struggling with a hyper puppy - I would recommend cutting out the processed treats......
