baldy patch on back

rocko has got a baldy patch on his back that he keeps biting,
i looked through his fur with a mini microscope i've got and couldn't see any mites or fleas rockos also started to bite his back legs aswell.
he's got vets at end of the week.
thankyou for all the advice.

If it's mites you won't be able to see them even with a magnifying glass - you can only see them under a microscope.

If it's itchy then it could well be mites so the vet'll be the one to help.

Awww poor baby do you use preventative flea treatments may be a idea ?

hes been put on a prescription flea treatment from vet.
my friend says i can use allery tabs on him tht may stop irritation but not sure if this is true.

You can use piriton, but as he's so young, I'd be inclined to see the vet first.

If you do give piriton, only give a half tablet maybe once or at most twice a day & if there's no change in a week, then stop.
