A pet dining table capable of adjusting a height or a slanting height of a table, wherein a table top is fixed between two opposite legs, and the two legs are oppositely arranged with a plurality of vertical spacings on the front and rear sides thereof. The locking hole is fixed, and the first locking hole at the upper end of the front side is at the same level as the second locking hole at the upper end of the rear side, and the locking hole vertically arranged on the rear side is also long. The slot shape is such that the front and rear sides of the end faces of the table top are correspondingly provided with locking holes, so that any locking holes on the front side of the table legs and the locking holes on the front side of the table are locked by a locking component to be combined. The back side of the table can be turned horizontally or slanted, and the locking hole on the back side of the table and the locking hole corresponding to the horizontal or inclined side of the two legs can be combined by another locking component. Therefore, the desktop can be locked horizontally or obliquely between the two legs, and at the same time, the height can be adjusted according to the height of the pet.一種可調整桌面高度呈水平或斜設的寵物餐桌，是包括兩相對的桌腳之間固定一桌面，該兩桌腳側面相對設有其前、後兩側分別垂直列設相同間距的數個鎖固孔，並令前側邊上端的第一個鎖固孔與後側邊上端的第二個鎖固孔呈同一水平高度，同時亦令該後側邊垂直列設的鎖固孔為長槽孔狀，復令桌面的兩端端面的前後兩邊亦對應設鎖固孔，進而讓桌腳前側的任一鎖固孔與桌面前側的鎖固孔透過一鎖固元件鎖固而使結合後，該桌面後側可轉擺呈水平狀或傾斜狀，再令桌面後側的鎖固孔與兩桌腳後側水平或傾斜對應處的鎖固孔可以透過另一鎖固元件鎖固而結合，故令桌面不但可以呈水平或傾斜狀的鎖固於兩桌腳之間，同時又可依據寵物不同身材高度而做合適高度的調整。
