zack suddenly started putting on weight too in the past month. Sounds like he and Robbie are twins. zack is a year old this month, and he weighed a little over 16 pounds when i weighed him about a week ago.
About a week or two before that, he weighed 15.0 pounds, so that was a quick weight gain. A few weeks before that, he had weighed less than 14.5 pounds for months, for about 6 or 7 months, his weight didn't change, it just stayed a little over 14 pounds.
With him gaining weight this month, i've reduced his food portions a little. It may be he gained weight because for about 3 weeks, i was mixing Stella and Chewys freeze dried raw meat patties in with his Evo--the patties have a high fat content. he loved it but i've stopped it due to the weight gain. He still visibly goes in at the waist and all i can feel is muscle and bone, no fat, but he looks thicker overall and i don't want him ending up overweight.
also, in the past month, i have not been taking him to the dog park, only twice. I was taking him several times a week but due to life circumstances, i have stopped. he just gets an hour a day walk now.
By the way, at the pet store, they told me Innova Evo now has a low fat version, about half the fat of their regular kind. But they didn't carry it in the size i need. i'm going to have them order a bag for me, they will take it back and give a refund if he doesn't like it.
