It may be a bit to much in the chest as the larger sizes to get a bit bigger around the chest circumference.

If your dog is 7 months old- and he is that long already he will likely fill out quite a bit-slower to mature. Since I don't know your dog's girth measurement what I can tell you is that the velcro strap under the body is pretty long and allows for a lot of adjustment. Whether it is enough is hard to say, but I could imagine this will fit him eventually. My malamute mix doubled her weight from 8 months to 1 yr, but only grew about 20% taller and longer. Hope that helps.
