As you point out, dog size, for one. But also the dog's reason for barking/nipping at the vacuum, how he/she feels about being led with a collar, etc.
Obviously, Charlie has a very positive attitude toward you taking charge via his collar, which is great. That speaks of a lot of effort on your part with him, since I remember how it all started with his training.
B - The cats.
Exactly! I use ginger or a mix of orange and ginger essential oils for cats, but lavender's good, too, as you discovered. I use lavender for cleaning and wet wipes.
Yes, if the litter is not as clean as they are used to, if anything disturbs them - strangers, new animals in or outside, etc. And, of course, a UTI.
My only warning would be that some essential oils will mar some surfaces. Always try them on a small spot where it can't be seen. Also, watering them down can help. Using them pure makes marring even more likely.
Yes, it will need refreshing periodically. It will be interesting to see how often. The amount of time will change, depending on how strong you make it.
C - I hope that the vinegar works for you. I've had luck with it the little I've used it, but have found that it 'wears off' quickly. Maybe that was just for my purposes. I didn't put it outside, because I have usually had some cats of my own outside.
Though, it's pretty good for disrupting certain bugs, like trails of ants.
I hope that it works perfectly for your purpose!
Speaking of using a lot of essential oils...you can buy some brands in pretty good sized bottles. I buy lavender in a large bottle, since I do clean with it. (It's great for combating germs!)
The last time, the large bottles were on sale at a local shop. I'd have to look, but think that it was Now brand. When buying new brands, read the label carefully to make sure that it's a pure essential oil.
I've picked up new brands, and had them be fragrance oils, which aren't the same. Luckily, I've always caught it before buying.
Pretty much I have my go-to brands at this point, but sometimes a good brand comes on the market.
Thank you for sharing these, and please let us know how the vinegar works for keeping the critters at bay!
Love All Life, Thank You For Posting! :)
