There is no optimal number of treats per day for a dog, and it’s not necessary to give your dog treats every day, says Hodges. “Take into account your dog’s current weight and lifestyle. A younger, leaner, more active dog can be given more treats than an older, heavier, more sedentary dog,” she says. “Monitor your dog’s activity level and weight regularly and you will, over time, develop a good sense of how to help them maintain a healthy weight.” If you’re unsure and would like help with your dog’s diet, check with your veterinarian or a board-certified veterinary nutritionist for guidance.
