My dog a mix with a springer and a lab, has these seizure type things that have been getting worse over the past month. We just got him from the SPCA a month ago. He curls up his back and cannot walk. He drools a lot and starts breathing really heavy. He also crys very quietly. And is very disoriented for about 10 minutes. After words he is really tired and loving. I am very worried I am taking him to the vet today.
