As the saying goes, "You can be a thief for a thousand days, but you can't guard against a thief for a thousand days." It's incredibly difficult to completely prevent thieves from stealing. When you're on guard, you're bound to let your guard down, and that gives others an opportunity. It's like your own dog; if you don't want it to get pregnant so early, you can put it in safety pants, reduce its contact with other dogs for a few days, or keep it indoors and watch it closely. When you walk it, keep it on a leash, and go straight home after your walk; don't linger outside, and never let your dog out of your sight.
If a dog doesn't see its owner, it might get pregnant. For example, this friend has a Golden Retriever that was on its period, but he didn't pay much attention and continued to play, eat, and drink as usual. After a while, he noticed that his Golden Retriever seemed to have a big belly!
The owner was still puzzled. She had always kept a close eye on her dog, so how could she be pregnant? The key question was, whose dog was it? What kind of puppies would they be? She noticed the neighbor's poodle was looking at her dog strangely; could the poodle's puppies be the neighbor's?
Four months later, the puppy was born, but it didn't look like a Teddy at all! It looked more like a mixed-breed dog. The owner was quite upset, never expecting his dog to give birth to such a litter of puppies! But they looked quite cute and adorable, so he raised them himself and kept one at home.
The owner was very puzzled. Why did this mixed-breed dog look so fierce? And it liked to howl like a wolf all the time! Its doghouse had also been thoroughly destroyed. The owner was really confused. "Is this dog even a mixed-breed?"
Not long after, the dog grew up, and the owner immediately recognized it as their puppy: they had wronged the neighbor's Teddy; this was a purebred Husky! Its howling, fierce eyes, and tendency to destroy dog beds were all obvious Husky traits! Why hadn't they considered this possibility?
Now the truth is really out!
