I checked Jake's collar this morning and I could barely get a finger under it so I had to remove it until I get another one. Three weeks ago, I had adjusted it to it's maximum of 22 inches and it was very loose at that time. Every time I weigh him, he still continues to fill out and gain more weight. He is currently at just over 95 lbs and is 26 1/2" to the top of the shoulder. At 9 1/2 months I thought that he might stop growing but not yet it appears. At what age can I expect him to stop growing?
