PROBLEM TO BE SOLVED: To provide an intellectual training toy for a dog which does not allow a dog to learn an efficient way of taking out a favorite article quickly and can continuously keep the dog interested.SOLUTION: An intellectual training toy 1 for a dog disclosed in the invention includes a cylindrical inner container 10 which can house a favorite article in the inside and a cylindrical outer container 20 which can fit the inner container 10 in the inside. The inner container 10 has an inner opening part 11 in a prescribed angular position on a circumferential surface, and the outer container 20 has an outer opening part 21 in a prescribed angular position on a circumferential surface. At least one of the inner container 10 and the outer container 20 has the inner opening part 11 or the outer opening part 21 of a different opening area in an angular position other than the prescribed angular position. The inner opening part 11 and the outer opening part 21 form an opening part 2 from which the favorite article is discharged by being superposed on each other. The inner container 10 can be fitted by changing the orientation in the circumferential direction with respect to the outer container 20, and the opening area of the opening part 2 can be changed by changing the orientation of the inner container 10 in the circumferential direction.COPYRIGHT: (C)2015,JPO&INPIT【課題】 犬が嗜好物の効率的な出し方をすぐに習得できず、持続的に興味を持たせることができる犬用知育玩具を提供する。【解決手段】 本発明に係る犬用知育玩具1は、内部に嗜好物を収容可能な筒型の内側容器10と、内部に内側容器10を嵌合可能な筒型の外側容器20とを備え、内側容器10は、周面の所定の角度位置に内側開口部11を備え、外側容器20は、周面の所定の角度位置に外側開口部21を備え、内側容器10及び外側容器20の少なくとも一方は、所定の角度位置とは異なる角度位置にも、開口面積が異なる内側開口部11又は外側開口部21を備え、内側開口部11及び外側開口部21は、重なることで嗜好物を放出可能な開口部2を形成しており、内側容器10は、外側容器20に対して、周方向の向きを変えて嵌合可能であり、内側容器10の周方向の向きを変えることで開口部2の開口面積が変更可能である。【選択図】 図1
