A place to share Pet Advice.
There is a dog training method I plan to use this summer. Here's how it works:
When you want to start doing this method, spray the area where you want your dog to go with training spray. This will encourage them to go in that certain spot. Next, take your dog outside to explore. Let it roam around and play. If it has to use the bathroom, encourage them to go in the bathroom corner. If they end up using the bathroom, even if it's not in that specific corner, praise them and give them treats. Allow this to happen a few times to get them used to the outside bathroom.
Now take it up a level by taking them out every 20 or so minutes every day for a while. After the first or second week, remove their training pads. This method can take anywhere between three weeks to two months, depending on the dog.
Now your dog is used to going outside, and they will cry by the door if they need to go.
If you have a kitten, don't let him/her outside alone for a couple weeks. Be outside together, look after him/her, and when he/she got used to being outside, teach him/her to come back to a certain sound (e.g. you calling him/her). After these, you can let him/her out alone, but for a short time. As the time goes by, you can leave him/her outside alone for longer and longer time.
