I peaked at the Nutrisource formulas. IMO there is not a significant enough difference between them and the TOTW I am feeding now to justify the 30% price increase.
However, I dug pretty deep into the Sportdog Elite formulas, as well as the Black Gold Salmon formula. KCal/KG, protein/fat ratios, carbs, and cost to feed are all very close to the TOTW that I have been feeding (within $12 a month from the cheapest to the most expensive). However, they do have calcium and phosphorous levels that I feel are more appropriate for a young, “large breed” dog. The Omega ratio also looks better, and they have lower ash content (which is expected due to the higher calcium/phosphorous levels in the TOTW).
I would have to order the Sportdog, and I get a pretty substantial discount on Black Gold and TOTW locally which makes the Black Gold about $150 a year cheaper for me to feed. Black Gold also claims the highest digestibility (96% VS TOTW 87%, and “high” from Sportdog). Smaller puppy piles are always a nice bonus…
I think unless I can find some substantial reason not to, I am going to try the Black Gold, and consider a rotation with Sportdog…
