I don't know if it's OK, but I have little choice. I have 18 elm trees that loose branches any time there is a breeze. They range from little twigs to 3" thick branches. It doesn't matter what the size is, they get chewed on and sometimes end up in the house.
I suppose that is never okay, but dogs will be dogs, just be careful. A while back Lily got one embedded in the roof of her mouth and we ended up at the emergency vet for a very expensive bill...all for a silly stick.
I also have several big trees in my backyard, sticks and twigs are unavoidable. I suppose each dog is different, my two hounds have never shown any interest in sticks. They eat (and throw up) grass very often, but thats it.
those hug branchs was funny. We are like one of the above posters. A Lot of trees. We live in a sub-division and have cyclone fencing. Tummy is almost 6 yrs. old. He gets a good quality fod. Let him outside and he goes right to dirt and twigs every thing. We found a basket mask. It is All holes (sort of like a hocky players) He can drink water. Tummy is indoor dog. If it is really hot- I let him out with it in for aBOUT 5 MIN.S to go potty
I don't let mine chew sticks. My neighbor's dog had a throat puncture that nearly killed him. As she said at the time, it was a good thing they had a college fund for the kids -- that was the only way they could have afforded the surgery and the three-week daily trips to Tufts for dressing changes.
