Have you just bought a bag of dog food and wondered how long it will last before it needs replacing? Perhaps you are wondering whether you should pick up another bag now, while you can. Either way, the following calculator will help give you an idea of when it will likely run out:
How Much Should Your Dog Eat Per Day?
The amount a dog should eat depends on two primary factors; their age along with their breed (and subsequent size).
The following are general recommendations for adults of the different breed size classifications:
- Toy Breeds (3-6 pounds): 1/3 cup to 1/2 cup per day.
- Small Breeds (10-20 pounds): 3/4 cup to 1 1/2 cups per day.
- Medium Breeds (30-50 pounds) 1 3/4 to 2 2/3 cups per day.
- Large Breeds: (60-100 pounds) 3 to 4 1/2 cups per day, plus 1/3 cup for every 10 pounds over 100 pounds.
For puppies, a simple rule is to feed them 20g per 2 lbs of their body weight per day. So, if you have a puppy weighing 10 lbs, they will need ~100g (0.2 lbs) per day. This equates to around 2 cups per day.
Regardless of your dog’s age, it is essential to check in with your
Treats should make up no more than 10% of your dog’s daily total calorie intake.
Using these numbers, you can therefore begin to work out how long your bag should last in the calculator above or reference table below.
