I booked a dog at the owner's house. And I met the dog and it was fine. Then they wanted me to watch their parent's dog as well, but I didn't get to meet her (I know, I should have met her) And they said she's fine. I came into the house this morning and the dog was super aggressive, but in her kennel, but any time I get near the kennel she barks, shows her teeth and I'm too scared to let the dog out of the kennel. I'm not sure what I should do. I told the owner that this dog is barking and that someone might have to come to get this dog even though the whole family is out of town. I just feel bad because the dog is super stressed and will be in the kennel for a long time today and I just need some advice.
