Here's a breakdown:
* Low-set and carried low: This is a common position for German Shepherds, especially when relaxed or standing still. The tail may be slightly curved but hangs mostly straight down.
* Curled over the back: This is also common, particularly when the dog is excited or alert. The tail may be curled in a full circle or a partial curve.
* Straight out and wagging: This is the classic sign of a happy dog, and German Shepherds are known for their enthusiastic tail wags.
* Tucked between the legs: This is a sign of fear or submission, and it's not necessarily a bad thing, but it could indicate that the dog is feeling anxious or unsure.
Important Note: The way a German Shepherd carries its tail can be influenced by several factors including:
* Mood and temperament: As mentioned above, different positions can indicate different emotions.
* Breed standard: While the standard encourages a tail that is "well-furred, reaching almost to the hocks, carried slightly below the level of the back", it doesn't dictate a specific position.
* Individual personality: Some German Shepherds may naturally carry their tail higher or lower than others.
* Health: If the dog is injured or in pain, the tail may be held differently.
In conclusion, a German Shepherd's tail position is not always held down, and it can be influenced by many factors. If you're concerned about your German Shepherd's tail position, it's always best to consult a veterinarian or a professional dog trainer.
