Well first id like to say that when medicating our fury animals its important to be extremely careful. Ultimately you have to make the right decisions for your pets. I have a lab who is 13+ years old. Over a period of the last few years she has developed osteoporosis, likely some arthritis, has had two ACL surgeries (one on each leg), and a dislocated hip due to the osteoporosis (surgeon essentially cut a part of the ball-of the leg bone that connects to the hip so muscle would grow in that area to reduce the likelihood of dislocating it again). So as you can probably tell she has trouble walking and is in some pain. When vaping I started to give her small amounts of secondhand vap and noticed she seemed to enjoy it. Lately other family members have noticed that she gets alittle hyper after administration (starts rolling around) and sometimes hungry but then she passes out (deep sleep). At times I used to see her legs twitching (possibly due to the pain), I have noticed less twitching (makes sense she goes to deep sleep after all). The next day we have noticed she even walks alittle bit better (possibly due to her being well rested not too sure). Either way I am seeing only positive effects thus far, I am always careful to slowly increase dose and have been watching for any negative effects. This is in contrast with one of the medicines that the vet told me was an option (which I read reports of one of the side effects being internal bleeding). I am so happy to have found something that seems to be helping her in a very noticeable way. We continue to monitor her and make sure she is still having a good life (we know if pain gets too much we might have to one day make a decision) but thus far she seems to be overall enjoying life. Not all dogs seem to react the same though, their biochemistry and weight logically have impacts. For example I gave a smaller chihuahua mix some second hand vap and she became too excited. I had to repeatedly make her lay down and rest, after awhile, maybe 15mins of laying on her side she went to sleep. This happened awhile ago and taught me to always be very cautious with dosage. Since discovering this, I have made a vapor lung and have been giving a small dose to my dog every night. Dogs noses are alot more sensitive than ours so the hits need to have a high air to vap ratio. Secondhand vap of the baby hits I take seemed good. With the vapor lung I only pull in vapor for a small portion of the bag then pull the rest fresh air which dilutes it and seems to mimic second hand vap.
