A Detailed Guide on How to Loosen Seresto Collar

Step 1: Determine If the Collar is Tight

The first step is to make sure that the collar is tight. An excellent way to do this is to put your finger under the collar and see if you can fit more than one finger underneath. If you can only fit one finger or none, the collar is too tight, and you’ll need to loosen it.

If the collar is not tight, then there’s no need to loosen it, and you can move on to step two.

Step 2: Try Loosening the Collar Manually

The next step is to try loosening the collar manually. You’ll need to find the adjustment buckle on the collar to do this. This is usually located near the clasp. Once you’ve found it, you can use your fingers to push or pull on the buckle until the collar is loose enough for you.

If you can’t seem to loosen the collar with your fingers, then move on to step three.

Step 3: Use a Collar Expander

If manual adjustments don’t work, you can try using a collar expander. This is a small tool that’s designed explicitly for loosening tight collars. You can find them at most pet supply stores or online.

Use a Collar Expander

To use one, insert the end of the expander into the adjustment buckle and then twist it until the collar is loose.

Step 4: Determine the Size of Your Pet’s Neck

Determine the size of your pet’s neck. This is important because you need to know how much slack to give the collar. There are two ways to do this.

If you have a flexible measuring tape, wrap it around your pet’s neck and take note of the measurement. If you don’t have a measuring tape, you can use a string or a piece of rope.

Again, wrap it around your pet’s neck and mark the spot where the ends meet. Once you have determined the size of your pet’s neck, add 2-3 inches to that number. This will be the new measurement that you will use to loosen the collar.

Step 5: Check the Collar for a Release Mechanism

The next step is to check the collar for a release mechanism. Most collars have a plastic or metal clasp that can be released with a squeeze of the fingers. If your collar has this release mechanism, squeeze it and slide the collar off your pet’s neck.

If your collar does not have a release mechanism, you will need to cut it off. Use sharp scissors and cut as close to the buckle as possible. You don’t want to risk injuring your pet by cutting too close to the skin.

Step 6: Adjust the Collar to the New Measurement

Once you have removed the collar, it’s time to adjust it to the new measurement. First, squeeze it and slide the collar over your pet’s head if your collar has a release mechanism. If not, you will need to cut a new hole in the collar using sharp scissors.

Once you have adjusted the collar to the new measurement, please put it back on your pet and ensure it is not too tight or loose. The ideal fit should be snug but not uncomfortable. In addition, you should be able to fit two fingers underneath the collar with ease.

If the collar is still too tight, repeat steps five and six until you achieve the desired fit.

Step 7: Call the Manufacturer

If you’ve followed all of the steps and the collar is still too tight, you should call the manufacturer. They may be able to provide you with a replacement or a refund.
