Labrador with allergies

[sunshine_sieben]

Thanks for your input, girls.
He's an outside dog.
No idea how I should give him an oatmeal bath... he's ginormous and heavy and not exactly cooperative ;-)
The Frontline angle is worth looking into. We use Advocate. Maybe that's when it started getting worse.
I think the heat and humidity are not helping him either at the moment although he has a large shady patio area (it's often the coolest part of the house. That area also has flyscreen all around it (it's more like a sunroom), so midgies and mozzies are at a minimum - not when he goes outside, of course.
It could be grasses. That was one of my first thoughts as we noticed it at the start of spring and because it's around his feet mainly. We've kept the lawn very short to keep that at a minimum, not sure what else to do, short of paving the whole yard....
There has not been a change in food at the time when it first started. But we have very recently changed to a cheaper one (we used to buy Eukanuba and just can't afford it anymore). No improvement or worsening since the change over. So I don't think it's caused by the food.

Thanks so much for the input. Keep it coming!
