Dog Refuses to Get in the Car: Causes and Solutions

He used to jump into the trunk without hesitation, but for a few weeks now he's been standing in front of the car, or worse, flat out refusing. Many owners interpret this as a tantrum or a sudden fear. In most cases, it's actually an joint issue.

Why the trunk is particularly difficult

Unlike a sofa, the height of a car trunk is often greater, and the air resistance when jumping puts significant strain on the hips and hindquarters—precisely the areas most affected by osteoarthritis or hip dysplasia in senior dogs.

Other possible causes

• A bad past experience (sudden braking, motion sickness) can create apprehension independent of pain
• A slippery surface in the trunk can be enough to make a dog unsure of his balance hesitate
• Excessive heat in the vehicle at certain times

But if the hesitation appeared gradually, without any identifiable trigger, the joint issue remains the most probable explanation, especially in a dog over 6-7 years old.

How to help him practically

The most direct solution is to eliminate the jump rather than waiting for the dog to overcome his reluctance. A ramp or a foldable step allows for gradual ascent without sudden strain on the joints. The same principle applies at home: low-step stairs for the sofa or bed address the same root cause, by reducing all repeated jumps in his daily life, not just the one in the car.

When to consult a vet

If the refusal is accompanied by lameness, stiffness upon waking, or a change in general behavior, a veterinary examination can identify the precise cause and rule out a more serious pathology requiring specific treatment.
