Dog food often contains higher levels of protein and fat than what is appropriate for squirrels. Squirrels are omnivorous and, while they do consume some animal protein, their diet primarily consists of plant-based foods such as nuts, seeds, fruits, and vegetables. A diet too high in protein and fat can lead to health problems in squirrels, including obesity, kidney issues, and digestive problems.
Additionally, dog food may lack important vitamins and minerals that are crucial for squirrels' health. Squirrels require specific nutrients, such as vitamin E, calcium, and phosphorus, which may not be present in sufficient quantities in dog food.
If you want to supplement a squirrel's diet, it is best to provide foods specifically designed for squirrels, such as squirrel feed, nuts, and fruits. These foods are more nutritionally balanced and appropriate for squirrels' dietary needs.
