Recommendation for dry food to help put weight on growing young dog

[sheena]

I have 3 border collies...14 years, 6 years & almost 1. They all get the same food with the puppy getting a bit more plus training treats.  Currently they are on Supercoat Adult, plus eggs, fresh (frozen) sardines, yogurt, chicken wings or drumsticks, & fish oil  The two older dogs do well on this, so much so that I have to watch that they don't gain too much weight. The old boy is going well for his age & the six year old is very active. However, the puppy (1 yr old) struggles to gain weight. He is very active & growing tall (his front legs come right up to his chin lol, & his back legs are so long, that when he sits, he sits like a frog.  He weighs 19 kilo & so far not desexed. I can feel his ribs & his backbone really easy, & I feel he is quite skinny... a bit like a greyhound with long hair.  

Am I worried about nothing & he is just having a growing spurt??  Or is there something I could feed him , apart from 100% raw (as we are camping & have limited freezer space).  I know I could feed him things like porridge, but would prefer it to be a whole food.  Looking for recommendations please that is readily available in our local pet stores

I have had this happen with adolescent sighthounds.There is nothing wrong with having a greyhound or sighthound build! If he is very active he may just have a marathon runner's physique, very lean, or his hormones are not doing him any favours. 

If he is otherwise healthy (and not losing weight) I wouldn't worry and wouldn't add anything except perhaps carefully add some extra oil, or feed another small balanced meal.

Nothing wrong with porridge. Proper rolled oats is, imo, a whole food. Just feed him this over winter. Or get supercoat puppy for him. Or just up his normal foods by 1/3.

No idea if this works...I tend to need to slim down fatties.  But if there's a real butcher anywhere near, you might ask about fatty offcuts.  I've often had to trim off and dispose of fat from chooks frames and brisket bones, and sometimes when I am at our local butcher I see guys in the background trimming off fat.
