Ok so tonight Ella was fine and playing with two other dogs that she is always around. All of the sudden, she started limping. She never yelped, there is no sticker or goathead in her paw, she just wont put pressure on it. I can bend it and she doesnt cry or anything, but you can tell it doesnt feel good. She just wants to lay down and keep it straight out. Thats how she seems most comfortable. I will take her to the vet if it isnt better in the morning... what could it be tho????????? she is barely 6 months old.....
