Hi Sully’s Mom –
42% protein is definitely not too high – my girls’ meals are generally in the 45% – 55% protein range. There’s really no risk of feeding “too much protein” to a healthy dog and this issue definitely would not occur with a kibble – most kibbles are much lower in protein than a natural raw diets due to the nature of kibble (a starch source is required for processing). When excess protein is consumed beyond what the dog’s body utilizes, the excess amino acids are catabolized into waste nitrogen, converted to urea in the liver and kidneys and excreted in the urine. This is a passive process that does not cause any harm or additional stress to the dog. I personally prefer kibbles with at least 30% protein. Victor Ultra Pro looks like an excellent food and I’ve heard great things about it.
