The number of treats you can give your dog per day will depend on several factors, including the size of your dog, the type of treats you are giving, and your dog's overall diet and health status.
In general, treats should make up no more than 10% of your dog's daily caloric intake. This means that if your dog needs 400 calories per day to maintain their current weight, they should only have 40 calories' worth of treats per day.
To determine the number of treats you can give your dog per day, you will need to consider the caloric content of the treats you are giving. For example, if the treats you are giving your dog have 20 calories each, you could give your dog two treats per day if your dog needs 400 calories per day to maintain their weight.
It is always important to speak with your veterinarian before giving your dog any new treats or making any changes to their diet. Your veterinarian can help you determine the appropriate number of treats for your dog based on their size, breed, age, and health status.
