When it comes to finding the healthiest food for small breed dogs, there are a few important things to keep in mind. It's important to choose a dog food that is specifically designed for small breeds; these foods are usually higher in nutrients and energy than large breed foods. Additionally, you'll want to look for protein sources that are easily digestible such as chicken, lamb or fish as opposed to more exotic proteins. Be sure to read the ingredients list on your food of choice; opt for brands with fewer additives and fillers, ensuring maximum nutrition for your pup. Finally, talk with your vet about any special dietary considerations that may apply for your particular pup based on its age or medical needs. With so many options out there, you're sure to find a healthy and delicious food perfect for your small breed pooch!
