If your dog only chases the female dog outside and is not in heat at home, it is not recommended to buy it. 2 Dogs can't be too stupid. If your dog can't learn anything after teaching, and won't go to the toilet after a few years of teaching, it is not recommended to buy it. 3. Dogs can't be too timid and jealous. Our products are pretty realistic. Some dogs saw the product and were afraid to approach it, or thought the owner had raised a new dog and was too angry to eat. In this case, it is not recommended to buy.But mostly that changed after they had known each other for a while. 4. The owner must be patient. Dogs are emotional animals too, and mating doesn't happen all the time. You can't expect a dog to have sex right away when he sees a toy. When you find that the dog doesn't use the toy right away, please give guidance instead of asking for a return immediately. Dogs may not be able to use them soon, but dogs with estrus behavior will use them sooner or later under the patient guidance of their owners. Many owners buy the toy for their dog, and if the dog happens to be in heat, it will use the toy. But some dogs are not in heat, so you need to wait for the dog to come into heat and then guide the hardened genitals into the silicone channel. After a successful first attempt, there is no need to help again. How to guide the dog to use it? The key is the time of the guide. You need to guide the dog when the dog is in heat. You can apply lubricate to the toy and help your dog enter the silicone channel. The dog will definitely use it. The toy has no female dog smell. Lubricants that smell like female dog secretions are not recommended. If the dog is not stimulated by the smell of the female dog, it will not come into heat, and it will not cause trouble to the owner.
