token.swapTokensForDividendToken(uint256) (#1220-1240) ignores return value by IERC20(husdtToken).transfer(address(devAddress),dividends) (#1238)
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 ticker (Space dog) 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.

token.swapAndLiquify(uint256) (#1174-1199) performs a multiplication on the result of a division:
-addHl = uint256(100).mul(_liquidityFee).div(_liquidityFee.add(lsDevFee)) (#1179)
-addNumber = contractTokenBalance.mul(addHl).div(100) (#1180)
Consider ordering multiplication before division.

Different versions of Solidity is used:
- Version used: ['>=0.5.0', '^0.6.12']
- ^0.6.12 (#14)

Remove unused functions.

Additional information: link

token._previousDevFee (#790) is set pre-construction with a non-constant function or state variable:
- _devFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Pragma version>=0.5.0 (#674) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
