4 lbs at 5 months...you must remember that these charts are used as a tool and in no way guarantee the weight. I'd say that your little man will be between 5 1/4 to 5 1/2 lbs at 18 months.
With that said, you must also take into consideration...are you getting him neutered, what kind of food will he be on? These must all be taken into consideration. |
