Content: His pilot study showed that dogs with more pronounced muzzles, such as Greyhounds, exhibited head-tilting behavior toward their owners more often than those with flatter faces, for example, Pugs. So, head shape and muzzle size may influence head tilting. However, more than one-half of the flat-faced dogs head tilted, so there may be more going on than simple snout issues. Goldman thinks Coren’s research is a great start, but points out that there could be more factors involved than just snout length. In the primate research, the visual acuity of the animal at certain ages seems to be related to head tilting. So, Goldman thinks looking at head tilting over a dog’s lifetime could be informative. “ Are we seeing more in puppies when their eyes are not fully developed? Or maybe when dogs become geriatric, and their vision (and hearing) starts declining, we see a re-emergence.” Positively Reinforcing Head Tilting
Goldman believes that we can influence head tilting by how we interact with our dogs. “ I think it might happen more often in certain dogs than others because it’s reinforced.
