Hi ,I'm new to posting. I have a 22 month old male brindle boxer. he was neutered at 18 months (july of this year). about a month after the surgery, he started shedding significantly. his coat was always coarse and thick and long for a boxer. you can now see his skin spots on his chest, which i never knew were there, and his underside is very bare. i wanted to know if anyone had an experience like this? i have heard of golden retrievers blowing their coats after spay/neuter and wondered if the stress of the surgery and lack of hormones caused this. or did he just lose his "puppy coat"? I am also considering food as an option as he still seems underweight to me at 63# even though we are feeding 4.5-5 cups daily. thanks for any input. will be taking him to vet for a wellness check in.
