I decided to bathe my guinea pig because he was starting to smell bad. I don't bathe him often just only when he starts smelling bad.
Step 1: Get the Materials
To bathe a guinea pig you will need your guinea pig, a couple of old towels, and some gentle baby shampoo. You need to use either special shampoo for guinea pigs or baby shampoo. Guinea pig's skin is very sensitive so you need to use gentle shampoo on it so it doesn't dry out.
Step 2: Fill a Sink With Water
I bathe my guinea pig in the sink, but you also do it in the shower. You will need to fill a sink with warm water. Don't fill it too much just up to your guinea pigs stomach.
Step 3: Place the Guinea Pig in the Sink
When placing your piggie in the sink, do it slowly to not scare your pet. Once your guinea pig is in the sink use your hand to scoop up some water and slowly pour it over your guinea pig. When the guinea pig is wet put some shampoo on its back and start lathering. Do not get water or soap inside your guinea pig's ears. Pick up your piggie and wash it's belly and paws. After that empty the sink and rinse the piggie with some clean, warm water.
Step 4: Dry You Guinea Pig
After rinsing wrap your guinea pig in a towel. The first towel will get wet from absorbing the water so wrap up your guinea pig in a second, dry towel. If your guinea pig lives outside, keep it inside until it dries. After washing your piggie keep them wrapped up in a towel, and out of the cold.
