It's a mystery why dogs drink out of toilets. It's weird, we know.
Some people say it's because they are thirsty and the water in the toilet is clean. Others say that dogs do it because they like the taste of urine or feces.
Still others believe that dogs drink out of toilets because they are looking for something to eat.
And some people think that dogs drink out of toilets simply because they are curious about what is inside.
Whatever the reason, we're here to explore all of these theories and try to find an answer to the age-old question: why do dogs drink out of toilets?

Drawn to the scent of urine
One interesting theory is that dogs are attracted to the scent of urine.
Toilets contain traces of urine, even after they have been flushed, and some dogs may be drawn to this scent.
This theory is supported by the fact that dogs will often drink out of toilets that contain urine but not feces.
Looking for something to eat
Another disgusting (but plausible) theory is that dogs drink out of toilets because they are looking for something to eat.
This theory is based on the fact that many toilets contain traces of food or other substances that may be appealing to a dog's sense of smell.
In some cases, a dog may even be able to find food in a toilet if it has been left there by someone who was eating while in the toilet.
If you do eat while you're in the toilet, please clear it - or else you'll start seeing your dog lick the toilet bowl and water (again).
Water source
A more likely explanation is that dogs simply see toilets as a source of water.
This is especially true if the dog does not have access to fresh water.
Dogs are attracted to the sound of running water and may be more likely to drink from a toilet because it sounds like a stream or river.

Thirsty
Of course, it's also possible that dogs drink out of toilets because they are simply thirsty.
Dogs need a lot of water and will often drink from any available source, including toilets.
If your dog is drinking from the toilet, make sure to provide fresh water in a bowl that is easily accessible.
Curious about what's inside
It's certainly also possible that dogs drink out of toilets because they are curious about what is inside.
Toilets are strange places and may contain things that a dog has never seen before.
In some cases, a dog may be attracted to the toilet simply because it is a new and interesting object.
This is especially so if your dog is recently rescued in the wild (i.e. feral dogs that never had human contact)
Trained to do so by their owners
A more sinister tone would be that they were possibly trained to drink out of the toilet, either intentionally or not.
If you grew up with a dog that drank out of the toilet, chances are your current dog does too.
Dogs are creatures of habit and will often imitate the behavior of other dogs, especially if it's something they see on a regular basis.

They do it for fun (and to annoy us)
Let's be honest, dogs do a lot of things just to annoy us.
Drinking out of the toilet is probably one of them.
It's possible that dogs drink out of toilets simply because they know it bothers us.
Or, maybe they just think it's fun. Who knows?
Conclusion
We're not sure why they do it, but we know that dogs love to drink out of toilets.
Maybe it's because they're thirsty, maybe they like the taste, or maybe they're just curious.
Whatever the reason, we hope this article has helped you understand why your dog likes to drink out of the toilet!
