It sounds very silly but "Yes" you can bathe guinea pigs i have two of my own i have a 5 month old male guinea pig and a 2-3 month old male guinea pig and they live in the same cage. I would only bathe the oldest one you have if you have more than one. The age would have to be 4 months or above because the babies get very scared.
This is how you bathe a Guinea pig:
1. put your guinea pig on the side next to a sink.
2. run WARM not hot warm water.
3. put warm water on your hands and gently smooth him.
4. do NOT drench the guinea pig only so hes a little damp and Do NOT add water on his face.
5. get a hair dryer and put it on the warm or cool mode on a low setting so its not blasting out.
6. smooth him whilst holding the hair dryer by him. DON'T put the guinea pig back in its hutch/cage until it's 100% dry or he can get ill.
That's how you bathe a guinea pig.
Look up bathing Guinea pigs on YouTube, there are plenty of informative videos there.
about once a week
It is fine to never bath your guinea pig. They dont need a bath because they clean themselves.
yes, you should bathe your guinea pig once a month.
If your guinea pig smells, it is most likely because you don't take care of if meaning you don't bath at reasonable times, clean its cage and wastes quite often, or maybe it is where you bought it that they have not cleaned it and its surroundings. Take these into account, and I hope this works!
I would not recommend giving a guinea pig any younger than 3 months a bath.
Once A Month...
when it stinks!!!!!!!!!!!!!!!!!!!???????????????!!!!!!!!!!!!!!!!!!???????????????
Yes. Surprisingly my piggy likes it a bit. But they don't need to take a bath that often. Don't just smell your guinea pig's cage, smell your guinea pig itself. Because the reason why your cage could smell it could be just the bedding, not the piggy. Hope this helped! Have a safe and happy guinea pig! But remember make sure the water you use is at room temperature, and do not wet your guinea pig's face.

guinea pigs bite them self because they are itchy SO GIVE THEM A BATH
i would say maybe a sink or if they don't have space there, then the bath tub.
You should not give a guinea pig a shower once a week. I only bath my guinea pigs if they are really in need of a bath or if I'm taking them to a show. I would say a few times a year if you want to bath them, but not once a week
