Him being my beautiful, funny, gentle and daft 10 month old Milo who, in the last month, has turned into the most awful Randy Pants. He will not leave either of my two spayed girls alone but especially Gracie and he has his nose permanently stuck up her bottom. As per usual he tried it on with her tonight and she nearly took his face off. He looked so crestfallen and I am now somewhat concerned that Gracie really might have a serious go at him if it continues. He humps anything and everything and walked across the garden this afternoon on his own doing the hump walk! Yesterday I found him trying it on with one of the cats, who just stood there and let him. He has always been very good off lead but will now take off after anything and the timing of this coincides with his change in behaviour. I was talking to a lady at obedience classes who has her five year old Beagle chemically castrated and I am trying to read everything I can about the various options. Milo is a lovely boy and in no way aggressive even with all this testosterone coursing around his body. He is my first dog puppy for many years and he is only 10 months old. As castration seems so final at such a tender age, can anyone offer any advice? Could this behaviour lessen as his hormones settle and what length of time are we talking about. Any advice would really be appreciated.
