AB - thank you for the nice words!!! I do try!
I also wonder how a diet issue could crop up so fast, other than, he was deficient, and now he's getting LOTS of good stuff... so things are just still getting aligned with his new reality. I'd give it a few more weeks at least and then see if things balance out on the carpal issue.
Sounds like you've got a great plan - and experience with the older dog, so my guess is you know what you're doing, and doing a good job... it's just the puppy going through some growing pains with all the changes in his life, making up for a lackluster beginning... but, that's just my opinion...
The only thing I didn't see you write was any organ other than liver. Even if non-organic, I think adding in some kidney would be beneficial. Chicken feet are also good raw materials for growing (and senior) joints.
If you are concerned, you can always grab some of the pre-made AAFCO certified "complete & balanced" raw tubes-o-food at the local pet shop, and give those as "supplements"... maybe as 1/3-1/2 the diet for a few weeks to fill in any holes you might be missing (not that I think you have any, though). I like Bravo and Red Rock brands (can't remember if they're AAFCO certified, though... but good for variety, anyway).
Here's a note I posted a while back about my weekly plan (updated to what's currently in the fridge)... I do use a spreadsheet still.
I put together a week's worth of food at a time to keep ready to feed - that way I can keep the meals balanced, but have leeway to mix things up during the week (feed more/less some days, etc.). One week's worth of food is about 21lbs total (barely 2% of her current adult weight of 155lbs). Based on the 80/10/5/5 model (meat/bone/liver/other organ) that becomes: |
|
5 lbs boneless pork (shoulder) |
2.6 lbs sardines (~5oz each, fresh-frozen whole fish) |
2 lbs pork ribs |
5 lbs ground beef (includes 10% bone, ground in) |
1 lbs lamb liver |
1 lbs pork kidney (soon to be bison) |
4 lbs green tripe (ground) |
Plus 2-3 eggs and ~1lb of frozen veggies (~3-4oz with breakfast: broccoli, squash & carrots) |
|
If you do the math, this diet is 82.4%/6.6%/5.5%/5.5% on the numbers. If I regularly give Denna 10% bone, she gets constipated... the veggies also help keep her poops softer and bulkier, which aids her anal gland issues (no veggies for a while, and she starts boot-scoot'n).
Denna does get a 1/2 scoop of Nupro Silver with breakfast - it has enzymes and probiotics, but also some added calcium, which you don't want until the puppy is well older than 6 months (best to wait for calcium supplements until they're over 18 months, or just avoid them all together... we don't use the Nupro for calcium, but I like all the other stuff it has in it).
About the calcium/phosphorus ratio - real, raw bone is in the proper ratio. period. So, as long as you avoid adding extra calcium (i.e. supplements or over-doing the egg shell), you should be fine.
Vitamin D... liver, kidney, egg and sardines should cover that need.

DMikeM has some experiences with growing imbalances... he used a supplement that included vitamin C. Vitamin C is good for all sorts of ailments, so I don't think it would hurt to include that for a bit. You might do your own research to make sure that's right for you and your puppy, though.
The only other thing I can think of, is to not try and "overcome" his past deficiencies with over-feeding him goodness, now. I'd keep him very lean and try to keep his growth as slow and steady as you can.

As for your vet - mine would have been right there saying the same thing. A home-prepared diet is an "unknown". Kibble is a known quantity... if there are any questions about nutrition, I would expect a vet to say go back to kibble... "just in case". But, I think you're doing the best for your puppy, and am glad you're going to stick with raw!
