My spaniel seems to have separation anxiety! He wo t walk with a dog walker. Hes 2. Always been walked by me or husband- husband has injured leg so now just me walking him. Tried a familiar dog walker but hes getting really stressed and wont walk with her- freezes, pulls to go back, lits of panting. Shes referred us to behaviourist,im waiting to hear back. Anyone had similar experiences? Or any advice?
