You might need the smaller size, if it closing her eye.

Max has gotten use to that, I don't have much choice in getting the bigger one for him, the one made for him doesn't fit his muzzle. Max has a very thick muzzle & a large mouth.

U should tell ur mom what is on the market for dogs that pull

1. choaker (doesn't work well)
2. spiked choaker (works mericals)
3. halti (takes time but also works mericals)
4. harness's (didn't work for me, nor the other dogs I tried it on, however I've seen it work fine on smaller dogs)
