I don't think you can overdose a 3 month pup with 1 capsule fish oil a day. I give the puppies 1 of the Kirkland brand from Costco and 2 to the adults.
So the Sam's Club ones I give my crew 2x a day could be used, but just give 1? Great! Thanks.
I get them from Costco and stick a pin in to squirt it on the food. Nothing in there to overdose on.
