I use lots of treats during training. I don’t use shop bought treats as that would end up being pretty expensive and I’m not sure how healthy a lot of them are.
I dry meat. It’s reasonably easy. It’s pretty cheap. Dried meat is easy to handle and doesn’t get your fingers smelly and greasy.
Good meats to dry are pig’s liver, chicken and beef. Not so much pork or ham as it has a higher fat content and doesn’t always dry well and lamb’s liver, as well has being more expensive than pig’s liver, is more crumbly when dried.
I then put the meat in the freezer, just so that it can start to solidify as this makes it easier to slice. Once the meat starts to solidify, take it out of the freezer and cut it into thin slices. Put the sliced meat in the oven. Meat has to be cooked at at least 70 degrees centigrade. I usually cook it at 80 degrees. Check the meat every hour and once it’s about half dry, take the meat out of the oven and cut it into long strips. Put it back in the oven and bake until it’s dried right the way through.
I break some garlic cloves and keep the meat and the garlic cloves in a ziplock bag. This might be a bit controversial as garlic is poisonous to dogs, but garlic is ok in moderation and my dogs love it, but you can leave it out if you want.
The treats will keep for ages if fully dried.
Break the strips of meat into very small pieces when needed.
Don’t forget to take into account any treats your dog has had when considering their daily food allowance.
