When I got my puppy at 3 months old she peed every 7 minutes on average. I was shocked so I actually timed it!
She's now almost 5 months old and is doing A LITTLE better. She pees the most in the evenings and can usually go for about an hour without peeing. If she's hyper it's still 3 times an hour.
I hope everyone's right and she'll be able to hold it longer and longer! I can't wait!!
