Head swelling up

[txhoghunter]

Ive had about four of my dogs in about a total of ten times head swell up. They will get a lump come up around the jaw area about the size of a golfball, within 5 days or so their whole head is swollen and sometimes eyes swollen shut. It last about a week or so then it will go down. My vet thinks its either snakes or spiders, but it too much of a coincidence for it to be always their head. Any ideas on what it could be? Thanks!

what do you bed your dogs down with? If you use straw i heard if they eat it it gets stuck in their gums and makes there head swell up really bad. i have never seen it but heard of a few hunters that had it happen.
