PuppyInuBsc.withdrawToken(address,uint256) (#284-288) ignores return value by _tokenContract.transfer(msg.sender,amount) (#287)
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.

PuppyInuBsc._transfer(address,address,uint256) (#154-188) performs a multiplication on the result of a division:
-devAmount = amount / 100 * devFee (#171)
PuppyInuBsc._transfer(address,address,uint256) (#154-188) performs a multiplication on the result of a division:
-liquidityAmount = amount / 100 * liquidityFee (#172)
PuppyInuBsc.swapAddLiquidity() (#203-221) performs a multiplication on the result of a division:
-devAmount = tokenBalance / (devFee + liquidityFee) * devFee (#208)
Consider ordering multiplication before division.
