For puppies or older dogs it is recommended that you choose the grain free flours. These are suitable for dogs over 12 weeks of age. It takes around 6-8 weeks for your puppies teeth to fully calcify, to be fully sure there are no issues I prefer to bake with 12 weeks in mind. Now with that said, I have a few customers who like me to provide puppy packs to send puppies off to their new homes with organic treats. If this is the case then I can bake at a lower temperature for a longer time period to get the softer biscuits. If you are a breeder and do require puppy packs then please contact me to discuss your requirements. The above applies to older dogs with loose teeth or no teeth, I can work to fit a biscuit your dogs will enjoy.
