My dog has boil on her
And I pressed some today
Maggots were coming out

What can I do please

I'm assuming you're talking about some short fattish maggots, if so drop some palm oil on the boils to make the maggots come out by themselves, if you are not squeamish kill them and afterwards bath your dog well with dog shampoo. That should take care of them and even ticks too
Also remember to bath your dogs regularly, it is good for their coat and skin

MYASIS! The easiest way to treat it is to get your vet to inject it for myasis infection. And try to “press” the ones you can if you will. But they will all die after the injection.
