If your puppy is avoiding their harness and running away from it, or being "silly" and turning it into a game, don't ignore it. And please don't chase them to get it on them!
This puppy shows the same response to his collar, so we're seeing generalized equipment avoidance. I've been working with him for a few weeks but this was a recent development. (Read on to find out why...)
Most dogs love their walks and are fine once the harness is on, but that doesn't negate the issue. Here are a few things I would recommend as a priority if you see this from your puppy, or even adult dog:
β‘Double check you have a well fitted harness. It should be Y shaped, not impact their natural movement, leave their shoulders free, not sit too close to the arm pits but also not too far down the ribcage. If you're still not sure, I've attached a free harness guide in the comments below!
β‘Stop chasing them and forcing it on them. Being silly and turning it into a game is likely your puppy showing fooling around behaviour: this is a type of fear response where the dog tries to "change the subject" to avoid the scary and uncomfortable thing happening, in this instance the harness.
β‘Don't just ignore it hoping it will get better. In very rare cases, if there is nothing else going on and the harness is well fitted, it might change with time. But in most cases I have just seen this behaviour continue or even escalate.
β‘Begin some gentle harness desensitisation, and in the meantime, have a risk mitigation plan for getting your puppy out that will still allow them to enjoy walks but not damage the relationship or experience further.
β‘Arguably most important, get a Dynamic Dog Assessment as a starting point. Why? β¬οΈ
The puppy in question is showing multiple signs of gait, posture and functional movement adaptations. Luckily his vet has taken it on board and he has been referred for further investigations. At his age (4-5 months) developmental musculoskeletal conditions start impacting behaviour. Based on our assessment, his response to equipment is fear avoidance due to body pain.
