Your question to an outside kennel, it will need to be tough. A GSD can chew almost anything , I think Canberra weather is way too cold to have Manny as an outside dog. Buy a extra large crate and keep him inside. Crate train your pup, they will learn to toilet train quicker there is a lot of info out there to google. GSD's need to be part of the family or there can be behavioural issues. Are you renting? is this the reason for the kennel outside?

Thanks, Sally Newman, for the oil of cloves, I swear cockroaches come into my house to die. Bombs do work well, but if you live in a cockroach infested area, they will always be back. Unfortunately, surface sprays give me headaches. If you ever have a mouse problem too, Peppermint oil sends them packing, just soak a couple of cotton balls and put them where the mouse has access. Neighbours - can't think of any legal solutions unfortunately.

Have you tried a mouse sander? We found them brilliant for fiddly bits - they have a "finger" accessory that makes life pretty easy. For the sections that are just too hard to get into even with a mouse, I hate to say it - but hand sanding using sandpaper wrapped around either a phillips head screw driver works well but it does take elbow grease, patience and time - remember that you need to sand with the grain rather than against it.

Feast Watson kitchen oil is 30-60 % petroleum naphtha. This maybe the reactionary problem. Ok time to fix. Sanding back starting with 120 grit and go through the grades...180, 240,320. Sand with the grain until you feel that all the blemishes are removed. Sounds daunting but the first strike with the sand paper is psychologically the most difficult. I'd stick to the Tung oil base and use Organoil danish oil. Brush on rub off with a clean rag. Let dry, sand back lightly, this time with 400grit and reapply oil and rub off. Let it cure for a couple of days and you should be good to go. Livos Kunos oil is also an option and would only take a 120 grit sand, apply, rub off. Let that dry for a day sand with 320 and reapply and rub off. The only problem is it is an expensive oil.
