I have used Dawn dish soap....very carefully...on stray kitten I found who was infested with fleas. There is a lot of controversy about this...and it is very drying to the animals skins. There 'may' be store brands that are now okay for puppies and kittens, so you may want to try that first. If you use it on the puppy be very careful with his/her eyes. This will only be a temporary solution, but it may get you started. :)
You can treat puppies with any topical flea treatment like Advantix. The puppies need to be 7 weeks old before you can use this product on the puppy. To treat a puppy younger than 7 weeks for fleas just apply the treatment to the mother and her close contact with the puppies will rid them of fleas.
no
feed it and find out
when she is at least 7 months old
I would not recommend giving a guinea pig any younger than 3 months a bath.
Yes unless you would like it in your house instead
I don't think so because if your 7 week old puppy gets tired, he/she should rest. But if they had lots of energy the day before and the next day don't seem to, then you should take them to the vet just to be safe.
you should test different types of food and find out which one he/she likes best.
Yes. Make sure that you use a very mild soap or puppy shampoo. Dont get any water in its ears and eyes. Make sure the pup gets dried completely before you give it back to the mother. Dont let it get cold.
It may be best to wait until it is around 6-7 weeks old, before you start giving it actual baths, instead try to clean it with a wet towel, using mild-warm water yea of course yhu can there are no problems with that at all
no that's how it's supposed to be if it's getting out of control take it to the vet
If it is a 2 week old gerbil, than its still a baby. I would say one should not be put in a sand bath until about 6-7 weeks, when they're more mature.
