yes, you should bathe your guinea pig once a month.
Once or twice a month. You can do it beginning and end of each month or twice a month if it smells really bad.
You can bathe a guinea pig 999,999,999,999,999,999,999,999,999,999,999,999,999 times.
you should atleast give them a bath 1 or 2 times a month
No.guinea pigs should have a bath in water at least once a month, guinea pigs are very prone to respiratory problems (breathing) and the dust could be very harmful to their lungs.
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
You should bathe your puppy/dog 4~8 times a month.
guinea pigs are fairly clean animals. u only need to give your guinea pigs a bath every 1 month. u can also use squeaky clean spray on guinea pigs.
Guinea pigs shouldn't have baths however if you think your guinea pig needs a bath you should give it a very shallow,warm(not to hot) bath and it will make it cleaner!
Once a week.
A dog should have one bath every week a month for optimal cleanliness.
I give my male pure bred shih tzu a bath every 2 weeks. A bath for your shih tzu every 2 weeks should do.
