According to the National Council for Pet Overpopulation, the top ten reasons that owners surrender their dogs to shelters are:

1. Moving
2. Landlord issues
3. Cost of pet maintenance
4. No time for pet
5. Inadequate facilities
6. Too many pets in home
7. Pet illness (es)
8. Personal problems
9. Biting
10. No homes for littermates

So, you see, great dogs have been left in shelters for reasons that could have been avoided through research. Above all, this shows that people need to make responsible decisions before getting a dog, to avoid adding to the pet overpopulation problem.
