An intradermal needle assembly for use with a prefillable container having a reservoir capable of storing a substance for injection into the skin of an animal comprising: a hub portion provided on the prefillable container; a needle cannula supported by said hub portion and having a forward tip extending away from said hub portion; and a limiter portion surrounding said needle cannula and extending away from said hub portion toward said forward tip of said needle cannula, said limiter including a generally flat skin engaging surface extending in a plane generally perpendicular to an axis of said needle cannula and adapted to be received against the skin of the animal to administer an intradermal injection of the substance, said hub portion and said limiter portion being formed as separate pieces, said limiter portion and said needle cannula being non-movable with respect to each other such that said needle cannula forward tip extends beyond said skin engaging surface a distance ranging from approximately 0.5 mm to 3.0 mm and wherein said limiter portion limits penetration of the needle into the dermis layer of skin of the animal so that the substance is injected into the dermis layer of the animal, said limiter portion defining an inner cavity receiving at least a portion of said hub and including an abutment engaging a corresponding structure on said hub portion thereby limiting the length of said needle cannula extending beyond said skin engaging surface.
