This is my third purchase. This time I bought two. I have two Golden Retrievers, both 32 kg, and they are 8 and 6 years old. I have been purchasing and using them every year, and it's half the price of buying them domestically! Although it's a bit inconvenient to have to add water directly, the cost-performance ratio is really good ^^ I quickly got used to the trick of adding water. Just lay the pad down, add water, and press it evenly, and it all goes in well. Before adding water, there's something that looks like powder, but it seems to turn into a gel-like substance when you add water. It seems like domestic products use a similar principle. When you throw away an old pad, it comes out like a gel.
I have currently purchased a total of 4 items, installing two each alternately. I am 100% willing to repurchase as this is an item that is necessary for dogs every year. I bought a product that I really like at a great price. Highly recommended!
