Whether you're training a puppy or an older dog, these bite-sized treats are a healthy reward. They're only four calories per piece, so you can indulge your dog when he learns to sit or stay without worrying about weight gain. Plus, each tiny piece is jam-packed with healthy ingredients like lamb and salmon (which is a natural source of DHA), without artificial colors and flavors or any of the stuff that can cause digestive issues, like grains, gluten, or corn.

Helpful review: "I bought these for my 8-week old pup and he took to them immediately. I love that their ingredients are meat and plant-based, not filled with grains. My puppy seems to love the flavor, and the scent is attractive enough to hold his attention but not so much it’s stinky."

For teething pups, these flexible bone rings are a must. For one, they're tough enough to soothe sore gums, yet they're flexible enough that they won't splinter or break while your puppy chews. Each ring is made from natural ingredients, including rice flour, vegetables, and chicken, and is fortified with DHA omega-3 fatty acids.

They're also completely free of potentially harmful ingredients like wheat and corn, and each ring is fortified with calcium and other nutrients to help pups grow strong, healthy teeth. Each of these large rings is 100 calories, but keep in mind that it is recommended that you break apart and give smaller and medium size dogs smaller portions of this treat. They are free of artificial colors and preservatives.

Helpful review: "My 3 1/2 month old German shepherd puppy is the love of my life but is going through a not so fun teething stage and is chewing everything, including me! I've tried literally every single chew toy and treat that I can find and most only last or keep his attention for a few minutes. As soon as I gave him one of these he ran over to his blanket, [sat] down and chewed for almost an hour! They are his favorite and definitely mine too!"

Helpful review: "I have a 7 year old female English Toy Spaniel. We got her at 14 weeks. She was born with stomach issues so she feels eating is not worth the stomach discomfort. We try every new food or treat hoping we can find one she will eat happily. She looooooves these!!! She begs for these!!! I love these even more since they are also healthy."

Helpful review: "This is the only treat I purchase largely because this is the only treat one of my dogs accepts. The ingredients are completely cruelty free and organic. The aroma is lovely yet not overpowering, and it’s clean to touch (not greasy at all). Already the convenient bite size, but you can easily break them in a half as well."

Thousands of reviewers insist these treats for dogs with allergies are a lifesaver for their pups with food restrictions. For one, they feature limited protein and carbohydrate sources that have been proven safe and healthy for most dogs. These bite-sized treats are made with all-natural venison and sweet potatoes and have no additives, dyes, grains, or chemicals. They're perfect for dogs with digestive issues, but also any skin allergies that may be exacerbated by food. They come in five additional flavors that include brown rice and lamb and sweet potato and fish. They come in two package types: each treat in the "all breeds" pack contains 30 calories, while the "small breed" treats contain eight calories each.

Helpful review: "I wanted to get something good for my dogs that wasn’t loaded with fillers and by-products ... They are grain free, apparently great tasting to my dogs (I’ll take their 'word' for it. I also like that it is limited ingredients, because one of my dogs has an allergy to certain ingredients, so I have to be choosy on what he eats. I do like the fact that they are thick, hard to break with your hands kind of treats.This is the first time I have actually seen my Belgian have to lay down and focus on eating the treat. He is actually enjoying it and not eating it just cause it’s there."

Not only are these hip and joint dog treats great for senior dogs, but reviewers rave about how much their dogs love the taste, too. They're made from real peanut butter and oats, giving them a slightly sweet taste, but they're also infused with all kinds of important nutrients and amino acids like glucosamine and fiber to improve your dog's flexibility and mobility while reducing pain and aiding in digestion. Each treat contains about 20 calories. They're even infused with egg shell membranes, which are dense in nutrients and great for your dog's skin and coat. And if peanut butter isn't your pooch's favorite flavor, they also come in beef and chicken. They're free of artificial colors and flavors.

Helpful review: "I'm back to buy my 2nd bag of these miracle treats. My [dog] had suffered a back injury in her lower spine in her previous home. The day after I gave her these hip action treats, she has walked normally now. I am delighted my dog seems to no longer have lower spine or hip pain. I will provide her with these forever."
