Now I have always been a believer that there is so much 'cr-p' on the Inet that one must make ones own decision.
Have fed a dog chicken necks for many a year .... However listening to this Vet... I thought I would take some time and research. One must be cautious......................
Overall there seems to be 'many opinions'
So ...."take my advice and please yourself"
Is it correct --- is it wrong .
Maybe worth a talk with your vet .. I did and recommended I cease feeding C/necks ?
