A dog with it tongue out can mean that it is:
- Panting: panting keeps your dog cool.
- Thirsty: offering water
- Hot
- Hungry: Feed or get treats
- Excited: Play with dog
- Relaxing: Your dog is relaxing and enjoying something.
- Stressed: Your dog may also pant while stressed or anxious or nervous. Take to walk or play
- Sick: If you are concerned that your dog's tongue is out to an unusual degree or are acting strangely, take it to a vet.
