My five week old Silkie was fine yesterday. Today (s)he is not wanting to hold her head upright. She keeps her head tilted to the right but can straighten it and turn to the left to look at things or to get food. She also randomly stops and walks in a circle to the right. She goes around 3 or 4 times, realizes shes going in a circle and goes back to walking straight. Ive heard of neck problems like this but dont know if its normal or fixable... help??
