Hi, my daughters chihuahua is in pain. She is usually the most active and playful out of the three chihuahua's we have. For the past week she's been in a lot of pain. She tries to play but instead she'll hold her head low and cry in pain. If she sits still for a while, she'll feel better, but immediately after she moves she's back to being in pain. She almost immediately starts to feel better when I hold her and rub her for a while, but little to no movement. I was doing some research online and others are saying that their dog had muscle strains, or pinched nerves. Their descriptions are very similar to what is displayed with my daughters dog. Also, the other issue is money is very tight for our family so having to pay for vet visits can become an issue for us. What can we do?
