Hi all, just after some advice. We had our Milo castrated 6 days ago now as we were looking at pro’s and con’s for castration and felt it was the best option for him. However, since having the operation milo hasn’t been himself which of course is understandable it has only been 6 days but he has become really aggressive, he sometimes is, if we pick him up or he does something naughty and we have to tell him off for, he will growl and snap at us and sometimes bite if we are too close. But it has become increasingly worse after his op. He is currently wearing a medical pet shirt as we felt the E-collar wouldn’t have suited him as he’s a little 3kg. So when we are trying to unbutton him for him to go outside and do his business he will try and snap at us and he’s very angry, of course this is maybe because he’s still sore there but in general he is moody too. We have tried the treat method and we have tried being very stern and telling him no, we have also tried being affectionate which is hard when you have a very angry chihuahua. We are really stuck and don’t know where to go from here, do we let it go over our heads for now as he is still recovering and tackle the issue after? Or do we stop it now? And how do we stop it? Any advice would be really helpful. Thank you in advance!
