Ratio Dry and complimentary wet food mix

Hoping there is someone out there that can advise me as I have been scrolling the internet and can’t seem to find an answer.
I have a Great Swiss Mountain Dog currently 19 weeks and 23kg I feed him on Simpsons premium puppy food as that’s what he came with from the breeder and wanting to add forthglades complimentary wet food.
He has 150g three times a day and unsure what I would need to deduct to add in the wet food, or how it is worked out?

Any help would be great!

Thanks in advance

Hello and welcome to the forum. As you have a large breed puppy I have asked David to reply to your question. Please keep a watch on your thread. He will respond as soon as he can.

Hi Swisslife and welcome! Mixing complementary foods with complete foods can be tricky. Does Forthglade not provide some sort of guide?

I haven’t personally found that forthglade has a guide.
Hence my confusion.


Swisslife - I am sorry that you haven’t been able to obtain a definite answer to your question. FWIW I think that it would be unwise to reduce the Simpsons by any less than 75% of the RDA. The reason that I say this is because puppies need calcium and phosphorous for bone growth, especially large breed dogs. Simpsons Premium Puppy Food is complete and contains these elements.

The Forthglade that you are using is complementary, not complete. I can’t see any reference to calcium additives on their website although it does say ‘minerals’ - just complementary range/just duck natural wet dog food (395g). If the minerals are calcium and phosphorus then that is less of an issue.

My suggestion is to reduce the Simpsons by 10% of the RDA and make that up with the Forthglade. Give it a few days and see how your dog goes, You could then try 20% if you wish.

Another method would be to continue with the Simpsons and just enhance it with some suitable home cooked food - see here. This provides variety, taste, aroma and additional nutrients.
