Deer are beautiful graceful animals that are scavengers but not necessarily hunters. Generally, they are not ones to pick fights or go looking for trouble; but they will attack if they feel threatened.
Pet owners may be surprised to learn that deer attacks on dogs do occur. It's not that the deer are looking to eat the dogs, but instead, they feel that the dog poses a threat to babies (fawns)- born in the heart of the spring season.
In the springtime, during April and May, is when homeowners will start to see an influx of deer on properties that are looking for food to eat from home gardens. This is when pet attacks from deer usually occur.
To protect pets from deer, it's best to build yard fencing in the yard that is at least 6 feet tall to block jumping attempts from nosy deer. Use a 7.5-8' foot high deer fence or pet fence for best results.
