BEP20.withdrawToken(address,uint256) (#747-752) ignores return value by tokenContract.transfer(msg.sender,_amount) (#750)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
Contract name (Polkadog-V2.0) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
BEP20.addLiquidity(uint256,uint256,address) (#1052-1065) ignores return value by pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,account,block.timestamp) (#1057-1064)
