Hi all the last day or so my bitch isn't her self , she seems tired and like she's been on a long hard run , she's hasn't been doing nothing game for a few weeks just a road walk so I don't think anything could be from it, she's 16 months and hasn't come into season yet , she's eating and drinking and s**ting fine , she's really struggling to walk properly tho so just need any suggestions before taking her to vets , thanks
