My dog is one of those shedding dogs where the hair doesn’t come off gradually, but rather it gathers at the butt and comes off in huge clumps every now and then. This would be easier to clean if she didn’t eat these clumps the second they fall off. She loves the taste of her own hair, and it’s disgusting. Should I be worried? Her poop now is so full of hair that it resembles the concrete of old houses. How do I stop it?

As funny as it may be, I would keep her consistently groomed and the house swept. Hair is certainly something that can cause an obstruction in large quantities. As you’ve witnessed yourself, it doesn’t digest.
