Hi Livercake, He has began to follow the scent of in season bitches that are walked in the park here, even as much as running accross the road after one

so i'm pretty sure castration will help with that. sadly when theres no in season bitches being walked then his recall is 100%

but he has started to become aggressive to other dogs and as far as i can tell its usually entire males and usually only when they approach me so i'm unsure if its a jealousy thing (for which i'm booked in to see a behaviourist once she's back off holiday) or if its because they are entire males so i'll be able to see if the implant helps and if so, then he'll be castrated.
I have read that castration can make a timid dog worse or make aggression worse depending on whats causing it and i'm also concerned that castrating him will change how him and my other dog are together so for those reasons i'd like to see what he's like with the implant first.
Miss Poohs... I know how you feel, i no longer enjoy walking Billy so something has to change but i'm reluctant to jump into castrating him incase it makes things worse and incase his issues are more behavioural than hormonal.
I do feel i have failed him though as i must be doing something wrong with his training if these problems are behavioural, its just such a shame because i adore the little guy and he really is a lovely dog apart from when he meets the occasional dog who approaches me and then he turns

and i have no idea how to deal with correcting jealousy so thats the reason i'm seeing a behaviourist also.
