The Dog Always Runs to the Pigpen - A Failed Free Romance!
There used to be a saying that you haven't seen a pig run unless you've never eaten pork, but now everyone can eat pork, yet there's hardly any chance to see a pig run, even in rural areas where pig farming isn't common anymore.

Raising pigs is actually quite hard, and you might encounter other unpleasant issues, such as the story below. This grandma discovered that her pet dog had been running outside for a while, often not seen during the day. She initially thought it was just playing, but accidentally discovered that it was constantly running into the pigpen.
To figure out what it was doing in the pigpen every day, the grandma secretly followed it, and what she saw made her gasp.

She saw the dog immediately jump onto the pig, and then they started showing affection, which was quite touching. The grandma couldn't help but laugh and sigh: 'Your relationship is too intense, it's a failed free love! You two aren't compatible!'

Haha, Dr. Xiao Ming doesn't know how to describe these two fellows. Are they giving each other dog food, or pig food? Whatever it is, they've been fed through the screen, phew~
It seems like Dr. Xiao Ming believes in cross-species love. No matter what kind of relationship this pig and dog have, it's definitely a bit too intense haha~

Dr. Xiao Ming explained: 'Although dogs have some navigational ability, free-range dogs are very easy to get into accidents, such as being hit by a car, poisoning from eating, fighting with other dogs, and getting injured. To avoid accidents, it's best to keep dogs within sight.'
In winter, dogs have reduced activity, and bathing frequency can be reduced. You can wipe off the minor dirt with a damp towel. But to prevent obesity, you still need to ensure sufficient exercise~
