Hi Erny
Yes, most definitely - earlier behaviours came back same as before. Also, he would get his penis stuck on occasion, and while this went away when he was on the implant, the problem returned. Not very pleasant for him or for us to have to put back in. Our vet told us that she's had to perform castration and radical penile amputation on a dog before who also used to get 'stuck' So both of these factors were the clincher, hence the desexing.
