Standard commercial feeds are not suitable for large breed dogs as:

Question

BlackTom AI · Accepted Answer

Assessing why standard commercial feeds might not be suitable for large breed dogs requires looking at common nutritional considerations for big dogs.
Option 1: 'Excess energy and protein are required to maximise animal growth' This is misleading because while growth demands ample nutrients, excessive energy and protein can predispose large breeds to bone and joint issues and obesity. Therefore this statement overstates the need and is not a general justification for unsuitability.
Option 2: 'Large breeds eat more and commercial feeds are not cost effective' Although some large breeds may consume more food, the question concerns suitability of the feed's nutritional formulation rather than cost. Cost effectiveness does not directly address nutritional adequacy or safety for growth, so this is not the primary reason feeds are considered unsuitable.
Option 3: 'The Ca:P recommended ratio is different for large breeds' This is the key factor: large breed dogs often require a different calcium-to-phosphorus balance to support proper bone development and reduce risks of skeletal disorders like hip dysplasia or osteochondrosis. Standard feeds designed for general or small/medium breeds may not meet these needs, making this option the correct rationale.
Option 4: 'They are less palatable for large breeds' Palatability can vary, but palatability is not the core reason standard feeds are considered unsuitable for large breeds. Even if some feeds are less preferred, the nutritional adequacy and mineral balance are the central concerns for large-breed nutrition.
In summary, the critical concept is that large breeds have distinct mineral requirements, particularly Ca and P, necessitating a different recommended ratio than standard formulas.
