A new guy and Sparkles.

[Gergraves]

Hi folks.Its a pleasure to be onboard.
Sparkles is a 13-14 yr old lab/English setter mix.The most amazing of the five previous I've raised.
Things have taken a serious downturn in New Brunswick economically and I find myself,for the first time,unable to pay for a vet.In my mind a person SHOULD have the means to sustain a pets health no matter what. I cannot as of late.
Regardless my question is: Sparky has a skin tag on his eyelid.It is "just barely" touching the eyeball.(if I pull his bottom lid down a bit it is obvious that it's not touching or growing inside the eyelid...YET).His one eye on occasion runs a wee bit.Hes a nervous breed and very self-aware regarding my checking him for anything but he does allow me to place a warm cloth on it which seems to comfort him a bit.It is approx 2mm wide and 4mm high.It isn't going high enough to obstruct his pupil but on occasion will paw at it a bit.
Is it possible to tie a silk thread on the tag being so close to the eyeball?
