Good question. Bentley was six when he died and I had some similar concerns with him as he aged, particularly because he had both of his ACLs operated on when he was 1 year and 3 years old. To answer your question, yes, I would definitely say 6 is a senior bulldog. In the last year of his life, I definitely saw Bentley slow down in a lot of ways and just change a little bit from the dog he used to be - playing less, getting up a little slower, a little more moody at times - but still happy and healthy. (Bentley did not die due to poor health!) I think it's great to be proactive about your dog's aging process but I also think it's worth mentioning that most of the dog foods that do contain glucosamine do not contain enough to make an impact on your dog's joint health so you might want to compare the glucosamine content in the food compared with what he would be taking if you were using a supplement and determine whether or not it's worth it for you to get that particular food, especially if he's doing well on another brand or formula.
Let us know how it turns out!
