They're a more purposeful, laid back dog, in most cases, than Pitbulls tend to be. There are exceptions, examples of both lazier Pitbulls and the rare American Bulldog with an inordinate amount of energy, but even then, it's not nervous energy, and such exceptions in no way disprove the rule.
Anterior blepharitis is commonly caused by bacteria (staphyloccus blepharits) or dandruff of the scalp and eyebrows (seborrheic blepharitis). It may also occur due to a combination of factors, or less commonly may be the result of allergies or an infestation of lice on the eyelashes.
1 If the condition affects the top, outer side of the front of the eyelids, it is called anterior blepharitis, a condition with a disease process similar to that of seborrheic dermatitis of the face and scalp. Blepharitis is an inflammatory condition affecting the area around the base of the eyelashes. 2  It can be acute, but that form is better described as eyelid infection (bacterial or viral), whereas chronic forms of the inflammation are diagnosed as blepharitis.
