OMG!!!!!!!!
That is just nuts! I cannot even believe someone would just take it upon themselves to cut YOUR dogs hair without even checking with you first. I suppose since she is your friend she thought it would be okay?????? But still..............and you didn't say anything about it to her?????? Maybe that was a good idea at the time (until you cooled off and got over the initial shock)....but are you going to speak to her about it or just let it slide. It's just hair....and it will grow back.....but still, like you said, you were in the process of growing his full coat; didn't she know that?????...........That was really stupid of her to do that; was she not thinking????? I would've freaked out.
