In 1860, still in England, Spratt unveiled Spratt's Patent Meat Fibrine Dog Cakes, a combination of wheat, beetroot, vegetables, and beef blood. Before long, he had competitors with names like Dr. A. C. Daniels' Medicated Dog Bread and F. H. Bennett's Malatoid Dog Biscuits. The products embraced the dubious science and the lightly regulated hucksterism of their era. (2009)[14]
By most accounts, the history of the industry begins with a man named James Spratt. An electrician from Cincinnati, Spratt had patented a new type of lightning conductor in 1850. Later in the decade, he traveled to England to sell it. According to industry lore, he had a quayside epiphany in London when he saw a group of dogs eating discarded hardtack, the cheap, tough biscuits carried on ships and known to sailors as "molar breakers." The first major chunk of today's pet industry was born.
If your dog exhibits a behavior you don’t like, there is a strong likelihood that it’s something that has been reinforced before. A great example is when your dog brings you a toy and barks to entice you to throw it. You throw the toy. Your dog has just learned that barking gets you to do what he wants. You say “no,” and he barks even more. Heaven forbid you give in and throw the toy now! Why? Because you will have taught him persistence pays off. Before you know it you’ll have a dog that barks and barks every time he wants something. The solution? Ignore his barking or ask him to do something for you (like “sit”) before you throw his toy.
When preparing homemade dog treats, make sure you take into account any allergies that your pet has to specific ingredients. You will want to avoid adding any ingredient that you suspect that your pet has reacted poorly to in the past. If you are experimenting with new flavors, only feed a small amount of the treat to your dog to see how she reacts to it before giving him an entire treat.

Fantastic list! I loved every recipe, until I read #23. I don’t care how little it is, bacon is not good for any animal (although it’s one of MY favorite foods and I’ll eat it, but I won’t give it to my dogs). I read one blogger justify bacon in their dog treat recipe by saying that for the number of treats that their recipe provided, one piece of bacon wasn’t going to hurt a dog. That may be true, but it’s not worth it. Boiled chicken might be used instead. I guarantee dogs would love it, and it would be safer for them. Just as a reminder, the American Kennel Club states:
