Punkin has gained .3 of a pound recently - but it's due to the cold and wet weather. We didn't think to reduce her food and she's missed a some 45 min walks in the past few weeks. We are now adjusting her food amount according to her activity level - less if it's not fit for walking that day.
We typically weigh Punkin every 2 - 3 weeks to make sure we are on track. It's soo easy to feed too much.
I wish I could be so disciplined for myself!
