Punkin gets some treats throughout the day - and often her treats are saved from her meals. Things like red peppers, apples, bananas etc. We weigh her every 2 weeks on a postal scale to make sure she hasn't gained anything.
We are conscious to feed her less on days when she is less active because it's too cold or wet out for walks.
Most days she gets a brisk 30 min walk - and if we can 45 - 60 minutes.
She is a lean dog, but the vet says that it means she will be generally healthier in the long run.
She weighs 8.5 pounds and the vert said 9 pounds is the absolute limit for her frame. The vet explained that dogs should have a waistline like people.
Now if only I could find mine
