Jake is 20 lbs at 13 1/2 weeks.
He was 8 lbs a 8 weeks
He was 18 lbs at 11 1/2 weeks
We've been having issues with chronic diarrhea that we're working through so he's not gaining as quickly as he normaly would. Vet is not concerned at this point ... he prefers to see them on the leaner side.
He's definitely growing though ... getting tall and long.
We have had a few days of normal stools, so we're hoping he puts a few pounds on before his next vet check and vacinnations on May 10th.
