Fair warning this video is graphic but all pet owners need to know about this. It normally strikes cats but sometimes dogs can get it to so it’s better to know about it than not to. It’s cause is a larva called a Cuterebra. It normally strikes during hot summer months. If you discover this on your pet you should get them to the vet right away and not try to remove it yourself because you wouldn’t want it to rupture and cause your pet an infection. It doesn’t normally get this large because it usually discovered much sooner and it doesn’t normally attach itself in the nose like this.
