I know that this has probably been asked many times before but I can't seem to find any previous posts.
Poppy is coming up 5 months old and is a miniature doodle. She is full of beans and energy and is LOVING her walks. She is off lead 80% off the time although she doesn't stray far from me unless there is another dog to go and say hi too!

I worry that I am exercising her too much as she is getting way more than the 'recommended' 25 min twice a day. She is out for about 45min in the morning, 45min in the afternoon and 30min in the evening.
If we do shorter walks or miss one out she becomes hyper at home and is nipping us and generally misbehaving! She also plays in the garden throughout the day and we do short sessions of training too. Are we walking her too much? If so, has anyone got any tips on how to entertain a bouncy pup without walking? Thanks for any help x
