Dogs, even just pets, are not a cheap investment. If you spend that average of $600 per year and your dog lives to be 15 years, the cost of the dog is $9,000. If you add in emergencies, illness, medications, if you are involved with canine sports, the cost can be easily over $10,000. Now you know the true cost of that dog. But for many, and myself included, the cost is worth it and we accept it as part of being a responsible dog owner!
