How can I tell if my dog has spear grass in her paw? Would there be an entry wound? She has had itchy paws between her toes for a while now but now one is swelling a bit.

Yes usually there is an entry wound with something stuck in the paw. The picture looks like she has an infection between the toes. This is infected interdigital cysts. It can affect one paw or all four. Often they have some drainage and swelling. I recommend taking Willow to the veterinarian for an exam. They will look for a foreign body in the paw and if it's a paw infection they will prescribe antibiotics. You can soak the paw in warm epsoms salt solution for five to ten minutes. This will draw out the infection and increase the blood supply to speed healing. If Willow is licking this excessively please use a restraint collar so she can't lick the paw. These generally heal quickly with treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Willow.
