The rule of thumb is pups can hold it for 1 hour per each month of age...plus an hour! So a 10 week old pup is capable of 3 to 4 hours. Sometimes they will be ble to go longer..but I wouldn't trust it for housebreaking purposes! I took Jake out every 30 minutes during the day nd right after playing or waking up. Also after eating they are ready to go very quickly. He made it through the night..from about 10 to 4:30 at about 4 months. He never had an accident in his crate and only peed once by the door. And that was my fault for letting my hubby be in charge! I was on him like flies on for 2 sold weeks. But that push really made a difference! Hope this helps!
