You don't know tired until you see a tired dog. Tesla usually spends every night running between my legs and demanding to go outside to bark at shadows. Today is Tuesday, the day my in-laws come over to watch Jake. They bring with them Pepe, a white furball and Tesla's closest same-species friend. They must go nuts all day because when night time comes around, Tesla is wiped out. She's been lying doggo on her mat since about 8:30 pm and shows no signs of moving until dawn.
