Oh boy my boys are jealous. My boys are brothers, same litter and almost 7 years ago. They will climb, crawl, and lay on each other to get closer to me. Fletcher though has really taken jealousy to a whole new level. A couple times when I was outside talking to company, I felt something warm on my feet, I looked down and he was MARKING me!
Also, now whenever he is tired and on my lap, if my nephew tried to pet him, he lunges and barks at him hard!
When I pet one, the other comes... when I give them each a new toy, they fight over 1 of them only. When 1 is on my lap the other one HAS to be on my lap too! Its terrible!
