1. **Decreased Energy**: If your dog is swimming slower than usual or seems to be struggling to keep their head above water, this could be a sign of fatigue.
2. **Difficulty Staying Afloat**: A tired dog may start to sink or have trouble maintaining a proper swimming position. Look for signs of their back end sinking or their head bobbing.
3. **Panic or Anxiety**: If your dog appears to be panicking, splashing excessively, or trying to climb out of the water, they may be overwhelmed and tired.
4. **Frequent Rest Breaks**: If your dog is taking frequent breaks to float or rest, it may indicate they are getting tired. They might also start to paddle less vigorously during these breaks.
5. **Heavy Breathing**: If you notice your dog breathing heavily or panting while in the water, it may be a sign they are overexerted.
6. **Unusual Behavior**: Look for any changes in behavior, such as whining, barking, or trying to swim towards the shore more frequently than usual.
To keep your dog safe, always supervise them while they are in the water, and provide breaks as needed. If you notice any of these signs, it's best to guide them to a safe area where they can rest and recover.
