REading your remarks and wondering. We have three little ones.The sisters Sugar and Spice and Pippo the puppy. Sugar gave birth 2 months ago to Pippo, a male and there seems to be a lot of pretty lively fooling around in the trio. They are racing through the house right now attacking each other (in a sporting way, I hope). I am afraid things will get out of hand. What should I look for? I'm sure this is an attempt to create their pecking order but nobody needs to get hurt. Advice??
