What is Terrible Twos for Dogs?

What is Terrible Twos for Dogs

You know how teenagers and toddlers alike become rebellious at some point in their lives?

They’re more irritable, bolder, and tougher to deal with.

The same happens with dogs, and dog owners like you and I sometimes call it the “terrible twos” for dogs.

This is the time when your once-behaved puppy starts acting rather unruly. He starts breaking certain rules you’ve established, he’ll even try refusing the commands you taught him!

Oh, this is such a messy period of your pup’s life. Unknowing dog owners will just shake their heads and question where they went wrong.

But don’t worry!

It’s just your pup’s normal way of transitioning to adulthood. With proper guidance, I’m sure you can turn him back to his usual well-behaved self.

Although you’ll probably experience seeing your dog become more dominant toward you and other dogs around him.

He’ll bark, chew on non-food items, and even scratch home furniture as well.

Your dog will do all these to test your limit and see just how firm you are with the lines you’ve drawn for him.

At What Age Do Dogs Go Through the Terrible Twos Stage?

Dogs usually go through the terrible twos stage around 6 to 12 months old. But this really just depends on every dog.

Some dogs may start their terrible twos earlier or later than others, which can still be called normal.

Just know that when your dog starts his journey from being a puppy to adulthood, terrible twos will soon happen.

How Long Does the Terrible Twos Stage Last in Dogs?

The terrible twos stage usually lasts from 1 to 2 years in dogs.

During this stage, you’ll be taken aback by how changed your dog may behave.

You’ll probably be surprised how wild, energetic, and vocal your pup is. 

However, you have to put it in mind that dogs are different from one another. How long their terrible twos will last depends on many factors. 

For example, pups who are properly trained by their dog owners will probably get over their terrible twos faster and in a short time.

Do All Dogs Go Through Terrible Twos?

All dogs go through terrible twos, they just have different ways of exhibiting their rebellious behavior.

Some may act calmer, others may manifest into a whole new different temperament. 

There are dogs going through terrible twos who only refuse to follow simple commands and become more excited over simple things.

But some dogs will bark their throats raw and chew on random things without bothering to hear what their dog owner has to say. 

These differences make some dog owners overlook terrible twos in their dogs because they think that their dog is only acting a bit differently, and not really as wild as terrible twos in dogs usually entail.

Is It Similar to Terrible Twos in Toddlers?

Yes and no.

The terrible twos in dogs are similar to the terrible twos in toddlers in a way that both young pups and humans try to test their boundaries by engaging in unusually challenging behavior.

However, toddlers should already be around 2 years old to go through terrible twos while dogs only need to be 6 to 12 months old.

And though both will have an unmatched energy and desire to do what they aren’t supposed to do, toddlers usually do this to express what they’re feeling.

Meanwhile, pups typically go through terrible twos to test the limits of their dog owner as to how far they can gain dominance.

What Happens During Terrible Twos in Dogs? (Signs)

More energetic

More energetic

He’ll be more energetic and playful, with a tendency to run around and ask you to play with him longer than usual.

Crossing lines

During terrible twos, your dog may start crossing lines you’ve drawn.

He’ll stop obeying your simple commands, and he’ll act more independently.

Your once obedient pup will seem to have lost his hearing because he’ll have a hard time listening to your commands.

Destructive behaviors

You’ve spent months training your dog to behave properly but terrible twos suddenly happen to him and almost all training went out of the window.

Yes, that’s a common scenario among households with dogs who are going through terrible twos.

These dogs will usually bark excessively, and forget to poop where they should chew on non-food items and such.

It’s like these dogs are indeed testing your limits!

Changes in hormone levels

If dogs are still not neutered or spayed when they go through terrible twos, the change in hormone levels may trigger them to act more aggressively.

They’ll be more possessive and territorial, especially the male dogs. Some of them would even develop the desire to mount or mate with other dogs.

How to Deal With Dog Terrible Twos?

Follow a routine

No matter how disobedient or rebellious your pup becomes when going through terrible twos, follow a routine.

Make him eat during the scheduled time. Don’t let him decide as to when and where he can eat.

Stick to the time he is supposed to play. Don’t let him extend his playtime, otherwise, he’ll think that he can get anything he wants.

Following a routine is your best way of making it clear that you’re the one who is in control and your dog should follow your command.

Reward good and calm behaviors

Terrible twos mean a lot of unruly behavior and messy encounters. Hence, on the rare occasion your dog behaves, reward him quickly!

Positive reinforcement like this will encourage your pup to show more of those good behaviors.

Increase exercise time

Since terrible twos increase your dog’s level of energy, you also need to increase his exercise time.

When your dog gets enough exercise in a day, he’ll be tired enough to finally just sit or lie down calmly in his spot.

Offer mental stimulation as well

Offer mental stimulation as well

You have to offer mental stimulation or brain games to your dog when he is going through terrible twos.

If your dog doesn’t get enough mental stimulation, he can become stressed or frustrated. And that’s the perfect ingredient for developing unwanted habits and aggression.

Counterconditioning and desensitization

Counterconditioning and desensitization are helpful if your dog is becoming socially challenged due to terrible twos.

With these, you’ll have to expose your dog to things that trigger their unwanted behavior. You’ll consequently have to reward him if he doesn’t show any negative reaction.

For example, your dog has become anxious around new people. Let him gradually meet a new face then reward him if he did well.

Provide appropriate chew toys

Your dog’s destructive behavior during terrible twos will be worse so give him appropriate chew toys.

Make sure you give him a durable and dog-friendly chew toy to avoid choking!

A good chew toy will surely keep your dog off your poor shoes!

Teach proper leash manners

Dogs going through terrible twos will resist all your attempts to keep them under. If you leash a dog during terrible twos, he wouldn’t like it. 

He’ll probably try to tug on the leash and walk you away from where you want to go, or even refuse to be leashed.

To keep this case under control, teach your dog proper leash manners.

Keep a close eye on safe play

If your dog is playing with another dog or a person is interacting with him, make sure you’re close enough to intercept if your dog starts behaving badly.

Don’t reward undesirable behavior

Don’t let your soft heart get in the middle of getting your dog back to his best behavior.

Stop giving him any unworthy reward if you know that he just did something bad!

In Conclusion: Do Dogs Go Through Terrible Twos
