This is a bit of a weird one but both my dogs are experiencing increased eye snot at the moment and it has changed in texture to how it normally is.  Usually they both have a wee bit upon waking and occasionally during the day but this is easily wiped away.  It is usually a greyish or brownish colour.

Over the last week they have both had an increase in the amount, the rott more than the staff and it has changed to a really stringy texture.  It doesn't appear to be an infection as neither of them have particularly red eyes, there is no green tinge to it and it doesn't appear to be bothering either of them.  They have both had eye infections in the past and this is different.  As strange as it may sound, the texture of the discharge is like the eye snot bull terriers get.  every bull terrier I have ever known has stringy eye snot rather than small balls of it but I think this is probably linked to the shape of their eyes rather than anything else.

I am wondering if this is co-incidence that it has happened at the start of the hayfever season and may be an allergy rather than anything else.  Does anyone have any experience or thoughts on this?

My allergy prone dog has the same issues - it always gets worse during high dust/pollen periods

If in doubt though do check with a vet and they can also advise what eye washes you can safely use if necessary

My Rottie Daisy used to suffer in the summer months with this type of eye gunge. She was originally diagnosed with Hayfever and the vet told us to bathe the eyes with cold tea bags, which did seem to help. It was only recently that another vet diagnosed entropian, and since her "facelift" she rarely gets any gunge.

Entropian was previously suspected last year but ruled out so sounds like it might be a hayfever type thing.  Looks like a trip to the vets might be in order but he is such a pest at the vets I tried to avoid it where possible.
