The big dogs gently cuddle up to their newfound hairy friends. The guinea pigs, completely calm and unimpressed by the powerful shape of their buddies, confidently contact their giant protectors. The pit bulls not only let them sniff them, they also lick them and hug them. In return, they also like to share one or two lettuce leaves with their four-legged friends. The little pets obviously trust their powerful roommates completely. That must be real friendship!
