We have a young male jrt he's just turned 8 months old. We have had him for just over 3 months. He has not been bothered by the fireworks at all, but tonight I went into the garden with him so he could have a quick wee before the fireworks started going off and a massive explosion went off very very close, he just carried on sniffing as he was, he didn't even flinch. I called him to take him back in and more started going off but he found a bit of stick and laid down to chew it in the middle of the garden! I had to pick him up to bring him in.
Told dh and he said he could be deaf. Is there another explanation?
