Dont forget you need to check your boars penis is clean they can get hay and shavings stuck in the foreskin.
Gently retract by pressing gently by base of penis and clean with baby wipes.
White sebum around the penis is normal but should not be offensive or smelly.
If this has a gritty texture this is a sign of calcium deposits which,can be a precurser to bladder stones.Some boars who have had little genital hygiene can be found to have hard calcium deposits around the penis,this can occlude urine output and cause bladder infections.
Occasionally boars can get thrush infections on the foreskin. This can present as a white discharge, so make sure you do genital checks as part of your regular routine.If you have any concerns see your vet.
Some boars can be prone to rectal impaction you will find a bulge in their rectum which is a collection of faeces.Gently press around the anus and the poop clump (best description) should gently come out,this is quite smelly !!This can compose of shavings,hair and poops.This sounds awful but the boar will often gladly eat this as it also contains the caecotrophs which is the type of poops that Guinea Pigs eat as part of their digestive process.
At the rescue all single boars who arrive aged 5 months to 18 months are neutered.
Neutering a boar will not affect his sex drive, never neuter in response to behaviour issues,only neuter if you want him to have a sow companion or if its for medical reasons.
Any anaesthetic carries a risk but in the hands of a competent small animal vet this should be minimal.We have had many boars neutered with no issues, and occasional post operative problems have been dealt with safely.
Immediate post op
Boars all recover differently,some seem as if nothing has been done,others are quiet and sleepy for the rest of the day.
Ensure your boar has fluids,syringe if necessary and put his favourite veg in to encourage feeding.Place a heat pad in his hutch covered in a towel,he will appreciate a warm spot to rest on.Just reassure him with kind words and let him rest.If your vet prescibes any medication ensure you complete the course.
Check the wound visually daily, wound closure can vary from vet to vet,most now opt for internal sutures and glue to the external edges,occasionally boars can develop a small abcess at the wound site or nibble !! so its important to check.He may need metacam for a couple days for post op pain relief.
See your vet if you notice any redness, swelling or the wound feels hot.
I house my post surgery boars on puppy pads / newspaper and hay for at least the first 7 days to avoid shavings irritating wounds.
A sow should NOT be spayed unless its a medical emergency,its much more complicated than a simple castration with a longer anaesthetic and recovery period.
Its vital for all surgery you use an experienced accredited small animal vet practice.
You will need to wait for 5 weeks post op before introducing your boar to a sow companion.
On guinea pigs rumps you can find a greasy spot at the base of the spine.This is the grease gland which, guinea pigs use to scent mark. Sows can have them, but it does tend to be boars who get greasy.
Its easily removed when bathing your guinea pig.Just apply a blob of Swarfega...yes swarfega... and leave for about 10 minutes.A little veggie snack tends to be a good distraction.Then bath your piggy gently rubbing the affected area,you may notice greasy hair being removed too,it will grow back.We often have neglected guinea pigs to deal with and are use to removing quite dense grease areas.
