I have 2 German Shepherds ages 4 and 8 who have been cycling through all the TOTW proteins for years. The 4 year old has some hair loss on his ears (no mites) and an irritation/infection on his hip. The 8 year old has had 2 urinary infections in 8 months.The Vet is always lecturing me on dog foods and is requesting I change off TOTW to one of these 2 brands. I will try a food change but not to these 2 brands. Any other thoughts? Thanks.
