Hi! We are fairly new to your forum but we do have a concern regarding our pup, Alfred. Alfred is a old English mastiff who is almost 7 months old. The past couple weeks now we have noticed that he is having problems with getting "started" in the mornings. His joints seem to be pretty stiff. Is this normal for such a large breed? He is about 105lbs. But it is concerning to us. Not sure what to do. Any suggestions would be greatly appreciated!!!! Thank you!!
