Thanks!!

Yup, Jackson's were 'runny' too, I felt like his eyes were always wet and running. It wasn't really like a goopy stuff either, just constantly running, like tears almost.
He has been outside both yesterday and today a lot... in long grass today too and still no eye drainage! So hoping the food is helping.
It's so difficult when you just don't exactly know and have to play the guessing game. I think I am going to go by his body condition and if he still seems hungry, etc... and like you said, weigh him, etc... I also plan on bloodwork next month to make sure everything is still running smoothly. The 3/4 seems to be sufficient right now, but it's so hard to tell. He also will often get a small-sized, or maybe medium, Kong filled with the low fat canned food so 3/4 + that is probably good for him. I will just adjust if needed

Thanks!!
I just did this doggie calculator thing and for an active adult 16lb dog, it says Your Dog’s Estimated Energy Requirement is: 553 kCal / day.
CN Venison is 463.0 kcal/cup (which surprises me actually? I think it's the same as Acana... which is a lot higher in fat/protein). Anyone good at math... (LOL??) if he's eating 3/4 cup of kibble per day, how many calories would that be?
