How many households own dogs?

I do not have access to real-time information, including constantly updated statistics like the number of households owning dogs.

To find the most accurate and up-to-date information on the number of households owning dogs, I recommend checking:

* The American Veterinary Medical Association (AVMA): They often conduct surveys and publish statistics related to pet ownership in the United States.

* The Humane Society of the United States: They may have data on pet ownership trends.

* National statistics organizations: Your country's official statistics agency (like the US Census Bureau) may have relevant data.

Please note that these figures can vary depending on the geographic location and the time period being considered.
