They rarely forget those things and this can be the underlying cause of their scared behavior.

How to Teach a Guinea Pig Not to Bite

If you know the old saying, “You can’t teach an old dog new tricks,” this can be completely applied to guinea pigs. If your guinea pigs are still young, you will be able to train and teach them how to behave.

Step 1: Scent and Connection

The first step is to allow your guinea pig to get to know you. You can accomplish that by daily keeping your hand on or in their cage for a few minutes. That way, the guinea pig will remember your scent and develop a trusting connection. Do this for a few days.

Step 2: Reward System

From there, you should monitor their actions. If the guinea pig comes to your hand without biting it, reward it with a treat. But if they bite you, don’t give them any treats. With this system, they will slowly start learning how they need to behave around their owner.

Step 3: Holding the Guinea Pig

Now, start with holding the guinea pig for a short time. Let them adjust in your lap. As time goes by, hold them longer, until they are able to relax completely.

Step 4: Have Patience

If they continue to nip you, don’t punish them, as any form of punishment can cause even more serious problems. Don’t give up and continue to try. Talk to them in a soft voice and don’t show anger or fear.

They will eventually stop nipping you. Always remember to give your guinea pig reward treats for good behavior. A guinea pig will slowly understand how to behave and they will acknowledge the treat as a reward for their good actions.

Why Do Guinea Pigs Bite Each Other?

Why Do Guinea Pigs Bite Each Other

If you are keeping more than one guinea pig in a cage, it is rather normal for them to bite each other. If this behavior develops into frequent violent clashes and fights, that could be a sign of battle over dominance. In these situations, it is best to separate them and keep the two guinea pigs in separate cages for some time.

There is another way that biting can happen and that is when they are cleaning each other. That is normal so you don’t need to break your head about it, but keep an eye out just in case.

Check their behavior from time to time, see how they are getting along, and look for changes in their relationship.

Why Do Guinea Pigs Bite Their Cage?

Why Do Guinea Pigs Bite Their Cage

If you have noticed that your guinea pig is biting the cage, these are the 4 most common reasons for it.

  1. Your guinea pig is bored. Sometimes their daily routine can be a little bit dull. In order to prevent this, add some new toys to the cage. There are a lot of items you can choose from. They can get easily bored if they don’t have something to do in the cage.
  1. It only craves attention. Guinea pigs can also feel rejected or ignored. Try paying more attention to them. Play or talk with them and show interest. If they have gotten used to having playtime with you, they will react negatively when you start skipping it.
  1. They are nervous. If something new is happening around them, like argues and fights, new pets, or anything significant that can impact their daily routine, it will cause them to be nervous. So, try paying more attention to your guinea pigs and find the reason for their anxiety.
  1. They just need to wear down their teeth. If the cause for biting the cage is their teeth, you need to add something they can wear down. Get them some chewing sticks to practice their teeth. You can also add a house or a hideout that they can chew on.

But if you notice that the chewing is becoming more intense and that the guinea pig is just not stopping, you should get an appointment with a veterinarian for a check on their teeth and gums.

What to Do if My Guinea Pig Bites Me When I Pick Her Up?

Learning to pick up and hold your guinea pig is very important. It is best to know all the tips for doing it properly.

Step 1: Getting Used to Each Other

For starters, let your guinea pig get to know you. Put your hand in the cage and let the guinea pigs learn your scent. Don’t take it out of the cage for a couple of days until it learns that it can relax around you. You should also be relaxed because they can sense anxiety.

Step 2: Petting

After a couple of days, put your hand in the cage and try to approach the guinea pig. Avoid chasing it around the cage but let it comes to you instead. Approach the cage carefully not to startle it and try to touch it softly with your fingers.

Avoid any erratic movement and loud noises. If you feel that it will bite you, just stop and leave this operation for some other day. It takes time for them to accept the owner.

Step 3: Learn How to Pick It Up

If your guinea pig now feels safe around you, try to gently pick it up. Use one hand to lift it, place it under the guinea pig, and use one finger to get around one of its legs. After that, use the second hand to add support to the guinea pig’s backside. Be sure that the grip is solid and firm. That way your pet will feel secure.

Step 4: Treat

Now you can put it against your chest and carry it. Don’t carry it too high and don’t walk too fast. Try sitting when petting your guinea pig. Understand that they need to go to the bathroom very often, so limit the cuddling sessions to around 10 min.

When you are finished, feed it with a treat. Slowly, your guinea pig will learn that after you pick them up, they will be rewarded with a treat.
