I was wondering if I could get some advice from you lot... 
We have a beagle staying with us while I friends stay in Hawaii (lucky bastards) for two weeks. He is a lovely dog but a little greedy, disobedient an smelly. These are all possibly relevant.
He eats anything and everything. We are very careful to only give him what he is allowed but he has eaten random crap off the beach and pavement. Had loose stools twice and farts that make your eyes water. Stools are better today but the smell is not. He basically smells all the time. He had his anal gland done before he came to us (the vet said it was 'thick').
Is the smell worrisome? Is he sick, is it the anal gland or should we consult someone?
He's happy and bright and affectionate. He's probably stressed because he's away from his family.
