I can tell something is wrong with her and i dont know what to do

Thank you for your question, I'm sorry your puppy is not feeling well. Chihuahuas can have problems where they build up fluid on their brain, and she may have a neurological problem that needs attention. It would be best to have her seen by a veterinarian, as they can assess her health, and let you know what sort of treatment she may need.

Fast, clockwise circling has been present in my boyfriend’s pup since he got her (about 2 years ago). She does this when she appears anxious (e.g. leaving the house; anytime we aren’t sitting or laying down), and when she appears excited (e.g. going outside, playing with toys, other dogs, and people). When we leave the house, we now have to keep her in the basement to prevent her from chewing on furniture or rolling on her own feces or urine in a kennel. She was on a anti anxiety med at one point but did not seek to help and gave her terrible diarrhea.

Hello anxiety can be very hard to deal with some days. There are many different medication and supplements you can try. I like calming bites. If this continues try looking for a trainer to help.

My dog don't stop circling and not eating what can I do

I'm sorry to hear this. Circling can have many causes including a toxicity, ear infection, brain lesion etc. Not eating can quickly result in low blood sugar and dehydration. You need to go to the vet ASAP for an assessment.

My Aussie began to lay down all day long and not move from the base of the stairs. Later in the evening he's gotten up continuously circles and bobs his head. He responds to sight and sounds. He looks so afraid in the brief moments he stops spinning. There's also an odor coming from his ears. I hope it's just an ear infection.

Thank you for your question. It is certainly possible that his ears are bothering him, and that can be quite painful for dogs. If left too long, the infection can spread from the outer ear to the inner ear, and getting treatment is necessary, as specific medications are needed to treat these infections. It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get any testing or treatment taken care of that might be needed.
