Personally I find using the Mdef & pdef buffs along with flesh ream & pounce most effective. If you prefer a bit less tanky & more offense oriented pet then Cynix' suggestion is probably best.
i have played veno since 2009.. i have always had for nix flesh ream/bless/claw/pounce. as for your dino.. on my battle fairy fox and my dino i use flesh ream *only cause i pk for pve bash is best* then i have claw and bless.. plus blood hunger... if ur pve. i suggest bash/strong/protect/reflect :3
