My dog isn't eating as much as she used to
Hello. I have a question and in consdiering the worst I suppose, my dog is about a year and 5 months old, we aren't sure what kind of dog she is but she has always had a VERY healthly appitite. For the last week or so, she has been taking maybe a bite out of her 4 cups of food she gets everyday. She is a very very entergetic dog, and she has been more withdrawn to my partner and she has alwasys been my baby so with me, she is fine. I've tried wet food on top of it, I've tried treats but she is nonresponsive. I plan on taking her to the vet but she has recently gotten a rattlesnake venom shot and she has to get another one at the end of this month, could this be a side effect? Mind we are in a extreme heat warning but I can not bring her inside but I have a tarp over her incloser and its actually very nice under that. I also have been putting a very large amount of ice in there because it is very hot. I'm worried for my dog and I don't know what to do or think.
