Every dog is different. If that works for your dog, keep it up. At that age, Beckie (toy/mini) pretty much went every 1-2 hours. She had a very immature bladder. She started getting better around 10 months or so. Now at 3 year old she goes 4-5 times a day like any dog would.
She has always remained a challenge though, as she gets easily distracted and sometimes will go outside but not do anything. I’ve had piddles when I got up in the morning because I didn’t watch her carefully the night before. She reminds me of a little 3 year old...
Teach your dog a potty command if you haven’t done it yet. It is a must !
