The circle of life is scary, upsetting, and normal. All creatures go through many specific stages in their lives, grow up, become old, then death comes along and takes them away.
Unfortunately, our loyal pups go through the same things, and it is heartbreaking because they deserve to be happy and healthy till the end of time, but again, this is just how life is.
If your four-legged best friend is becoming a senior, you must be well prepared and keep many things in mind in order to keep him as happy and healthy as possible. They have given us love since the day they opened their eyes, and now it is our turn to return the favor.
