how to avoid the T pose?

basically i'm making a script to attack and load the animation, i would like to know the logic or what i should do so that the idle or walk or run are not stopped / canceled when attacking, here is a piece of my code.

mouse.Button1Down:connect(function()
	if CanBite == true and CaughtPrey == false and Biting == false then
		CanBite = false
		bite:Play(0.2)
		Biting = true
		local stuff = char:GetChildren()
		for i, v in pairs(stuff) do
			if v.Name == "Head" then
				v.Touched:connect(function(hit)
					local human = hit.Parent:FindFirstChild("Humanoid")
					if human and hit and hit.Transparency ~= 1 and Biting == true then
						Biting = false
						human:TakeDamage(Dmg1)
					end
				end)
			end
		end
		wait(0.5)
		Biting = false
		wait(0.5)
		CanBite = true
	end
end)
