When mine first came home at 10 weeks we only gave him is complete kibble as treats. Your pups tummy might be a little sensitve when he first comes home, so make sure you follow the guide lines of what the breeder has been doing - that is if the breeder has been sensaible and given a decent food like James Wellbeloved.

When you know hes all settled then you can try other treats, also you have to be carefull about the size of the treat compared to the pup and how chewy it is (choking hazard)

Good luck with your new family member and put some pics on!!!
