My little Snickers came over and wanted to sit on my lap and when I picked her up her whole body was trembling. It would last a couple of minutes with a short break and start again. After a couple of hours I took her to the ER thinking it might be some form of seizures. She was tested and given an anti-bacterial medicine because they thought it was probably an infection and she was trembling from pain. I followed up with her doctor the next day and she continued her on the medicine because they had found puss in her urine. At the end of her treatment she had a culture to make sure the infection was cleared up which it was and she was obviously doing well. I turned in her claims for both emergency and primary doctors and they were paid within a few days. My experience with Pet's Best has been excellent. They were very responsive and when I have questions I call and am always treated with understanding and respect. I recommend them every chance I get.
