Has anyone had positive results using these?
Our 13 yo staffie is suffering from arthritis and I'm desperate to try anything now 
He's just finished a course of anti-inflammatory injections over one month, which has helped in the past, but seems to be less effective this time around.
He can't take anti-inflammatory tablets as his digestive system can't handle them (been the same since i got him a 2 yo - we have to manage that with prescription food and daily medecine).
He has food supplements to help (nutriquin) but I want to try this collar and see if it helps.
Brand is armadillo which seems quite reputable from looking at their website.
Any info / feedback gratefully received
