Know the signs of stress: First and foremost, it’s helpful to understand the signs of stress, anxiety, and fear in your dog. Your dog is becoming stressed when you see any or some of these… yawning, panting, licking of lips or nose, ears pinned back, a low tail, avoidance or mooneye where the white arc of the eye is showing. Doing what you can to lessen these negative responses early can help to deter the possibility of a more extreme reaction such as panic or aggression. If you know what situations stress your pet, you can better limit exposure to those stimuli.
Keep your cool: Strangely enough, one of the best things you can do for your dog is to remain calm yourself. Pets take many of the cues from their human parents. If you are rushed, anxious or irritated, your pet will mirror your behavior.
Speak in a relaxed tone. While in the exam room act at ease. If you treat the visit as a routine your dog will learn to also.
