Having been a nurse many years ago it goes against the grain to feed raw chicken let alone with the bones to anything. That said it's up to the individual to do what they are happy with.
I don't have a problem with anal glands with my cockers but my Basset does suffer or rather he did until I started putting either mini shreaded wheat or crushed weetabix on his Royal Canin.
Fingers crossed no problems for the past year
I was the same as you, ex nurse, brought up never to give bones to dogs especially chicken
When we first had Belle her breeder advised us that the best thing to keep her teeeth clean was a chicken wing a couple of times a week, I was horrified but found out on here that its common practice , still couldn't bring myself to give her one, read up a bit more online, and then finally very warily took the plunge, Belle has never looked back, she is 2 now and her teeth are sparkly white and never had a problem with her Anal glands. They really are a treat for her
. Monty on the other hand is not such a fan of Raw? he will eat a wing but it takes him ages and he is really unsure what to do with it still, but he is like that with whatever raw I give him, but I def think he is in the minority
