Using these Spotty pet waste bags is a breeze. First, take a bag from the roll. The arrows on the bag will show you where the opening is, so you can quickly get started. Turn the bag over your hand, and then pick up your pet's waste. Once you've picked it up, use the extra space at the top of the bag to tie a secure knot. This will keep any odors and mess inside the bag. When it comes to storage, keep the roll in a dry place. You can put the dispenser with the refill roll anywhere that's convenient for you, like by your door or on your pet's leash. Since these bags are biodegradable, you can feel good about disposing of them in the regular trash. Just remember, don't overload the bag as it might cause a tear. And if you notice any signs of damage on the bag before use, it's best to use another one. With proper use, these bags will serve you well in handling your pet's waste.
