Fish with grains

I’m a rather petite corgi- I appreciate the small morsel size. The vet said I need grains- I don’t know what those are but I am part of the clean bowl club!

I was giving Daisy Bell a Cana wholesome grains small breed recipe which she like very much but I wanted to switch it to fish meals instead. So I purchased the new low Northern catch small breed. I've been mixing it in with a regular fool little by little like they say to do but she just doesn't have the taste for it. So again I'm stuck with a whole bag. I should have just stuck with the acana wholesome grain small breed recipe which I'll probably go back to

Great tiki dog alternative

Since tiki dog was recently bought by a bigger company I was scared of the ingredients change. So I tried Nulo and my pup loved it and I love the ingredients. :

Our 12-lb girl has been eating Nulo grain free, small breed kibble either turkey or salmon since she was a baby. Looking for more options to change up her diet, I came across this blend including such good grains as oats, barley and millet. I was impressed by the ingredient list, and Lucy finds it tasty so it’s on our rotation.

Great food

Both I and my dogs absolutely love it. The first thing that caught my attention is the high-quality ingredients—real animal proteins like turkey, chicken, and salmon are the top ingredients, which is exactly what I want for my pets. I love that it’s free from fillers like corn, wheat, and soy, and it has added probiotics to support their digestion. Both my adult dogs have thrived on this food. My dogs are obsessed with the taste, and I’ve noticed fewer digestive issues and smaller, firmer stools since switching. Plus, their coats are shinier, and they seem more energetic overall. I also appreciate that Nulo doesn’t include any artificial colors or preservatives, and the brand uses sustainably sourced ingredients. It’s great knowing that I’m feeding my dogs food that’s not only good for them but also made with care for the environment. I highly recommend Nulo Challenger to anyone looking for a high-quality, delicious, and nutritious food for their dogs!

Trying Nulo northern catch, wanted to start adding more seafood options to my pups diet. The kibble size is perfect for their little mouths. I’ve started using as training treats which they both love! And I mix with their other food to give them variety. The biggest plus is that this food contains no legumes, potatoes, soy tapioca, corn or wheat!

Paws Up!

First time feeding my dog kibbles that use fish as its main ingredients. I was a bit nervous at first, fearing the smell would be too strong, but it turns out absolutely fine. My Shih Tzu eats it right away. But considering its higher protein level (38%), I think I may mix it with other kibbles (he’s on Purina usually). I love the package—the bag is actually resealable, which not too many manufacturers do it somehow. The size of the kibbles are quite small, perfect for small or even extra small breeds. Overall, I’m very happy about the product and I’m sure my baby will welcome some alternatives to his daily diet.
