@Natalie, first I have been to
Dolgellau for a day trip with my M&D when I visited them in Wales a few years ago. You need this well earned break!
Secondly and more importantly I am really feeling your stress in this post and I know how upsetting it is.
There is no right or wrong for Bear but you know your dog and what is best for him.
We have also used the implant for 2 years ,hoping we could "train him" as he might mellow with age and we could stop using Superlorin.
We would leave a gap between the 6 month implants. Hunter was about 14 months with his first implant, we did it to protect his elbows and joints.
After the implant we noticed a huge change in his behaviour. It actually took Hunter 3 weeks of "heightened senses" before it fully worked as they get a surge of testosterone when it is inserted. 10-14 days they told us.......not with my chocco idiot.
With the implant he still sniffed bitches on heat but no humping. He still humped his best mate Max who I think just smells really really good mixed with excitement of playing with his best bud. Max does seem to "attract" lots of dogs.
Hunter's focus was so much better, much easier to train with the whistle and he stopped his pulling for a 30s sniff every 1sec.
After the implant wears off ( 9 months the first time), he gradually becomes a porn star and this meant limping for a few days as it irritated his elbows/joints. In addition much less focus, very easily distracted, constant sniffing and marking and he can scent a bitch 800 m away!
This year (already 3) we really tried 6-8 weeks after the implant to re-train, but it was horrendous and a very frustrated dog, which was breaking my heart.
Lots of sleepless nights/crying/guilt and we decided to have the op.
4 weeks post op and his behaviour is nearly the same with the implant.
What is noticeable is that he is more reactive on the lead with big, male dogs and he is very vocal if I ignore him.
Yesterday he made no attempt to hump Mokka (having her first season) on his walk. He has humped Max (expected) and last week he did fancy a retriever at the beach but we stopped him "pre-mount". No frustration when he meets female dogs and I can relax when we go off lead in the woods.
I have to admit that I did feel bloody awful (lots of tears) after he had his op especially when he had a fight with his nemesis Boa. However his focus is bang on and he is loving the 3week recall challenge. Keeping his mind trained is just as important as physical exercise!
Bit of a waffle, sorry!
