He got into one of the nearby fields yesterday and now he has cheat grass embedded in his feet I got all of the ones that were in his left paw but there is still some in his right I can't see anything but I think that it may have gotten all of the way under his skin. His paw is so red and he ripped most of the fur between his claws out and it is all pussy he just started limping about 30 minutes ago. He won't stop licking it and it is to late to take him to a vet it is 1am here and the nearest vet doesn't open until 9 or 10 and I think by the time that comes around it will be so bad that they will have to operate on him - that is what happened to my other dog and it costed us almost 1000 bucks - my parents said that they won't pay for it if it costs over 50 because they just can't offered it right now - I am almost in tears what should I do. oh please help me!

He is in so much pain that he won't even let me touch his hut paw he is growling and showing his teeth at me everytime
every time I try to touch it

is there anything that i can give him for the pain should i rap it??
