Cimbi is growing up?

It seems that Cimbi has changed a little bit during this one week when we were away. He is calmer and more obedient, he is less excited about other dogs during the walks and he stays closer to us. This morning, when we got ready to go to the vet clinic to meet one of the rescued dogs he was always following us so closely that it was impossible to leave him at home - though originally we did not plan to take him as the other dog needed a long medical check-up and X-ray, so we thought that it would be pretty boring for Cimbi. But he made it quite clear that he wanted to be with us. So he accompanied us to the vet clinic and waited patiently. then we went to the park where he had a great time :))
