It's personal preference. I worry more about where the protein is coming from, the ash content in the food, the manufacturer of the food, etc.
But I personally am not too comfortable going over 18% fat. Also remember they are usually a 'minimum' so even if a food has a 18% minimum... technically, it could be much higher. Unless there is a maximum listed.
Honestly, small dogs generally need higher protein than larger dogs, from what I've seen as a trend in foods. Larger/giant breeds need the right amount of calcium/phosphorus levels in foods for proper growth, and often times for giant breeds, regular puppy foods are TOO high in protein/fat.
I've found that Jackson, my active 17lb boy, does best on foods that range in 25%-30% protein and 14%-16% fat. I typically don't like going over or under that. |
