Puppy Treats

Just wondered if you can give the markies type puppy treats to adult dogs?
Iv got a big box for my puppy from P@H [own brand] and they just look like the mini markies???
I give my senior dog a couple occasionally and she loves them.
I dont think they have anything in them that would upset an adult but just wanted to check with everyone on here first.
They are quite cheap and are enjoyed by my dogs as apposed to the actual markies, which are enjoyed by them but are ALOT more expensive, if they are allowed these treats as adults it would be great lol.

Actually have just found on the P@H website that they also sell adult marrowbone biscuits, look exactly the same as the puppy ones :s hmm.

Sorry to waste your time everyone!
