I have a puggle and she’s about 8 years and quite a bit overweight and isn’t highly active but she is puppy like playful when she does play. She woke up this morning in good spirit and very playful, ran downstairs and anxious for a walk. Towards the end of the walk she began to limp and has been like this all day. However, she still seems happy and in good spirit but has only put little to no pressure on that leg. When I went to check it out she whimpered when I placed firm pressure in the inside of her upper leg. There’s no visible wounds of a bug bite or splinter.
