Working out how many days one bag of tripe covers
Updated
How many days does a bag of tripe last? Divide the bag's net weight in ounces, which is 1.5, 2 or 4, by your dog's daily share in ounces from the treat budget calculator. That gives the days. Our guidance is to use an opened bag within 30 days, so choose the size that runs out inside that window.
How do you work out how many days a bag lasts?
You need two numbers, and only one of them is ours. Bags come in 1.5, 2 and 4 ounce sizes. The daily share comes from you.
Open our feeding guide for the treat budget calculator. You type in your dog's daily calorie number, from your vet or from your dog's food bag. The calculator uses a fixed 10 percent treat share and gives you weight in grams, as whole numbers, and in ounces, to one decimal. It shows weight only. It does not show days, so the last step is yours.
Here are the steps:
- Get the daily ounces from the calculator, or use your vet's figure if your vet gives you one.
- Divide the bag size in ounces by those daily ounces.
- Compare the answer with 30.
In words, the formula is bag ounces divided by daily ounces equals days. If the answer is 30 or less, the bag fits. If it is more, read on.
Our tripe is sold raw and freeze-dried, so wash your hands with soap and water after you handle it, including after weighing a share.
What if the bag would outlast 30 days?
Then pick a smaller bag. Our guidance is to use an opened bag within 30 days, and the 30 days starts when you open it. A bag with more days in it than that is a size too big for how your dog eats it.
The smallest bag is 1.5 ounces, so the sizes run from there up to 4 ounces. If even the 1.5 ounce bag would outlast 30 days at your dog's share, it is still the closest fit, and our guidance for it stays the same: use it within 30 days of opening. We say nothing about price or value in this math, only days.
The reverse is simple too. If the 4 ounce bag comes out under 30 days, it is the one to look at.
That 30 day figure comes from Sniff and Shift, not from the label. Until you open it, a bag goes by the best by date printed on it instead.
Do topper days and training days change the count?
They can, because both come out of the same daily share. The bag says: "Feed as a treat or meal topper." A topper day and a day of training rewards draw from one pot, not two. A heavier topper day uses up days faster, and a lighter day gives some back.
So treat the count as an estimate. Weigh the share rather than eyeballing it, and our weighing guide walks through the kitchen scale routine. Weighing keeps your daily ounces honest, and the division is only as good as the number you divide by. If you want a figure for a heavy day, weigh that day's share and use it.
The three sizes are listed on the freeze-dried beef tripe page, and any of them can be the right one once you have run the numbers.
How do two dogs change the math?
Add each dog's daily ounces together before you divide. Each dog's share comes from its own entry in the calculator, so run it once per dog and add the two results. Then divide the bag ounces by the total.
Two dogs on one bag means fewer days from that bag, so check the total against the 30 days before you choose a size. Our guide for homes with several dogs covers the rest of sharing a bag, and this page only adds the ounces.
Questions
Does the calculator show days per bag?
No. The calculator shows your dog's daily treat share in grams and ounces, and nothing about days or pieces. You do the division yourself: bag ounces divided by daily ounces. The result is a number of days to compare with 30.
Why do the math in ounces?
Because the bags are sold by net weight in ounces, at 1.5, 2 and 4, and the calculator gives ounces to one decimal. Dividing ounces by ounces keeps the units matched. The calculator also gives grams if you prefer to weigh that way.
What if my vet gives a different treat figure?
Use your vet's figure instead of the calculator's. The calculator uses a fixed 10 percent treat share, so a different number from your vet replaces it. The days follow from whichever daily ounces you use.
Which bag suits a dog that finishes one fast?
The bigger bag, still inside the 30 days. If your numbers say a 4 ounce bag runs out well within the window, that size matches your dog. Run the division first, and let the answer pick the bag.
Does a second sealed bag count toward the 30 days?
No. The 30 days start only when a bag is opened. A sealed bag goes by its best by date, which is printed on the bag. Our guidance is best by 1 year from production, so keep the second bag sealed until you need it.
