Spiked Alpha Dog Bowl. Symbolic of brute strength, the Alpha Bowl has a dramatic physique made from cast aluminum with a polished nickel finish. The spikes provide a sleek, striking finish, giving your Alpha (or Beta) dog, the perfect amount of fearless. Removable stainless steel bowl. This is used and has some wear. Not sure if it can be polished? Still an amazing piece! Great conversation piece, funny, and super unique. Please zoom in on all pictures to see wear all over, especially on top where the bowl sits.
