Help, dog is sick!
I have an 8 month old Chihuahua who is not feeling well. Now, last Tuesday I did bring home a new 10 week old puppy. About 3 days ago my older chihuahua stopped eating for 24 hours and had some diarrhea on just day one of not eating. I did get her to eat a bit and just gave her hard food instead of her normal wet food to try to stop any loose stools, though she has previously been fine on wet food. She started eating again yesterday and only ate her wet food, but this morning she had pooped excessively overnight. Like 3 piles and pooped again while I was cleaning it up. The morning poop looked better and more normal, but she did not eat her breakfast.
I don't think she caught anything from the pup since the pup is not having any issues, but the older chi has been going to petco training classes. Maybe she got something there? She is fully vaccinated though. I'm wondering if maybe the food she is on just no longer agrees with her. I have always fed my dogs Hills Science Diet because that has worked for them (please don't start a big dog food lecture, I'm posting about my dog's sickness not food, everyone can and should feed what their dogs do best on). I have ordered some Canidae food after getting a recommendation from another dog owner and think I will start mixing it in with the older chi's food to see if things improve. Eventually I think I will switch the new pup to it as well though she seems to be doing well on Hills Science Diet.
The thing is, she has not been lethargic and is still active and she and the new pup get along. She has had semi bad gas on ocassion. If she still seems a bit under the weather though I am taking her to see the vet. Any advice is much appreciated on what could be causing this. Like I said, the issues started a few days after bringing the puppy home, not the same day.
