Are the inner pet and the big pet produced by the same manufacturer? What's the difference between them?

The inner pet and the big pet are indeed produced by the same manufacturer, called "Shuoteng". I was curious before, so I checked it out. I also know the difference quite clearly, mainly at four points:

1. The big pet is an insect repellent for dogs, cats and exotic pets, and the inner pet is a special insect repellent for dogs;

2. The big pet is an insect repellent to drive the body inside and outside, and the inner pet is an insect repellent to drive the body inside;

3. The big pet is a drip insect repellent, and the inner pet is a flake insect repellent (pork flavor);

4. Big pets use it once a month, and inner pets use it once every three months.
