yeah, true about the pennies...and I saw an episode once of "Emergency Vets" where this green iguana swallowed a bunch of coins, too.
Oh, I'm glad, Barbaro!
What do you consider large? What is the dog's breed/mix or weight?
For my two Rotties - one is little for the breed at about 65 pounds; other is low-average for adult female at 75. I also love sardines so sometimes we share them. Then each dog might get one or two - depending on amount in tin - and then I have some.
Have also given each dog all the sardines from the container, it ends up being about 4-5 sardines. My dogs are raw-fed and used to eating fresh and whole food. But I don't always use the whole can per dog.
If your brother wants to try it, start slowly, especially if the dog has a "sensitive stomach", has a serious systemic problem like organ disease, or is elderly. So maybe - depending on weight/type of dog, try one little sardine from the can or container. If the dog is fed twice a day , you could even half that one sardine so each meal the dog has half. Gradually build up to greater amount.
Sardines with the bones is also a great source of fresh calcium
Pumpkin is great to have available for digestion issues - loose poop or constipation, either way. We always try to have some in the pantry.
Should be plain pumpkin - NOT "pumpkin pie filling".
I either get organic BPA- free canned, or have some frozen squash of some kind, so that if one of my dogs has some digestive thing, I have the pumpkin right away ready.
Remember - sardines in water, not tomato sauce or oil or mustard or something.
