Theses are probably the best treats that I have used to help me in basic training and teaching of tricks to many dogs of many diffrent sizes. The smallest of which being under five pounds and the largest being well over 100. Not one of them had been unwilling to eat this treat, all of them salivate and get excited at the crinkling sound of the bag being opened. As long as the treats are broken into sizes that are safe for the smaller dogs to eat, and the dog is always supervised while snacking, they have no problem chewing or swallowing. The treats are very easy to break up into smaller pieces, which comes in handy with even the extra large sized dogs, because they can be given one at a time. This can really come in handy when training or teaching them almost anything if the dog is treat motivated since they will have to do the same thing receptively in the beginning and don't get bored when they get treated.
