Hello Greg
Your hedgehog definitely needs to see a carer. Details of the BHPS number are on the front page here. You also need to do this as quickly as you can or it will die. Once you notice a problem with a hedgehog you have a very small window of opportunity to get it treated so please get this hog proper help asap.
Regarding routine treatment of hogs the simple answer is no.
Hedgehogs pick up internal parasites normally as part of their diet, and externally due to wandering around in the undergrowth.
They are perfectly used to dealing with these parasites themselves – it is only when they become ill or stressed that the parasites can start to take hold and cause issues. If you start to routinely treat you will cause more problems to the hog as it loses it’s ability to deal with things naturally.
I will also point out that it is illegal to treat a wild animal for no reason.
I hope this answers your questions. Please get help for the hog in question before it’s too late
