How to Introduce a New Supplement to Your Dog

Start with a plan

Adding something new to your dog's day is easier when you have a plan before the first serving. A little preparation helps you stay consistent, notice how your dog responds, and answer your vet's questions if they come up.

Before you open the container, check with your vet, read the full label, and have the batch or lot number written down. Our list of questions to ask your vet can help you prepare for that conversation.

One new thing at a time

This is the most useful rule of all. If you start a new supplement, a new food, and a new type of snack in the same week, and something seems off, you will have no way of knowing which change made the difference.

• Introduce only one new product at a time.
• Hold off on other changes, like switching foods, for a couple of weeks.
• If something else must change, such as a planned trip, consider waiting to start until things settle.

Take a fresh look at the serving guide

Even if you have read the label before, read the serving guide again right before you start. Weigh your dog so you are using a current number, not a guess. Then find the right row for your dog's weight and stick to it exactly.

Our guide to daily serving by weight walks through weighing your dog at home and splitting a tablet if your dog needs a half serving. Do not give more than the guide lists, and never double up after a missed day. Just continue the next day.

Same time, with or after a meal

Pick one time of day and keep to it. Many owners find it easiest to give the flavored tablet with breakfast or dinner, or right after. Tying it to a meal makes it part of something your dog already expects, and it makes it much harder to forget.

• Offer the tablet from your hand, or set it in the bowl with the meal.
• If your dog is unsure, try offering it right after they finish eating.
• Keep one person in charge, so no one in the house gives a second serving.

Keep a short notes log

A simple log is one of the best tools you have. It does not need to be fancy. A notebook by the food bin or a note on your phone works fine. Each day, write a line or two:

1. The date and time of the serving.
2. The amount given.
3. Whether your dog took it readily, slowly, or not at all.
4. Anything you noticed about appetite, energy, sleep, or behavior.
5. Any other changes in the day, such as travel, visitors, or a new walk route.

Keep the log going for the first few weeks. Your notes give your vet real information if you ever have a question, and they help you see patterns you might otherwise miss.

Watch your dog, and call the vet with any concern

You know your dog better than anyone. During the first days and weeks, pay a little extra attention. Notice how they eat, how they act on walks, how they sleep, and whether anything seems different from their usual self.

If anything concerns you, stop giving the new product and call your vet. Bring your notes log, the label, and the batch number. It is always fine to call with a question, even a small one. That is exactly what your vet is there for.

Storage tips

How you store a supplement matters. Follow the directions on the label, and keep these habits:

• Cool: keep it away from stoves, sunny windowsills, and hot cars.
• Dry: avoid the bathroom or anywhere near a sink or dishwasher.
• Sealed: close the lid tightly after every use, and keep any half tablet in the container.
• Out of reach: store it high up or behind a closed door, well away from curious noses and paws, and away from children.

Keep the product in its original container so the label and batch number stay with it. If you want to double-check the testing paperwork first, our guide to reading a supplement label and COA shows you what to look for.
