Signs of over-exercise in dogs can be tricky to identify, so here are a few indicators to look out for: Exhaustion: your dog may seem excessively tired, more so than usual after a walk. Overworked muscles: they might start panting to try to remove excess heat, they might tire towards the end of a walk. Joint concerns: if they’re reluctant to go for a walk or have difficulty going up the stairs, they may be experiencing occasional joint stiffness. Paw pads: their paw pads may become red, sensitive or sore if overused. Behavioural changes: if your dog suddenly changes temperament and becomes more anxious or irritable, it could be a sign that it’s no longer enjoying the level of exercise they're doing. If you notice they’re more reluctant to go for a walk or have difficulty rising after resting, it’s okay to give them a break, and you should speak to your vet. Rigorous exercise can lead to health concerns, including for their joints, so your dog might not enjoy too many daily activities, like long runs or steep hikes. Identifying whether your pet might be doing too much exercise can be tricky.
