I have a 1 year old chi/doxie mix (female) who is normally very peppy and eager to play. However, she is very lethargic today. She woke up and had a normal BM and ate breakfast, but not with her normal vigor; I had to call her back to show her the few bits of food left in her bowl. She has no other symptoms – no crying, no vomiting, no diarrhea – she just wants to rest/sleep and/or be held. She is a rescue dog I’ve had for a month and, in that month, she’s done a lot (new home with new dogs, road trip to visit grandma and another new dog, puppy sit for grandma this past week). Could it just be stress? My plan is to take her to the vet tomorrow if she’s not her normal self by then; any other suggestions?
