You may have noticed how your dog's pupils get big when playing and may be wondering why that happens. Interestingly, this is not something exclusive to dogs. Many cat owners report seeing this happen in their kitties as well.

Some dogs hate collars and this can obviously put a dent in their ability to enjoy walks and the many perks of being present in the outdoor world.
