I know my girl is not going to get any taller, but I was wondering if these dogs normally have a filling out growth spurt around 16 months of age? My girl is right around that age and her activity level has not increased, but she acts like she is hungry all the time. I'll feed her and about an hour or so later she starts licking her food bowl and looking at the cabinet where her food is kept. I'm feeding her the same amount I always have, so I know she's not starving. I don't mind if she fills out, but I don't want her belly to fill out though lol. Any input on this would be appreciated. Oh yeah I am sneaking in some treats when she acts real hungry, but I make her work for them (sit, stay, down etc.). Thank you!
