RepublicOfDogs.swapTokens(uint256) (#679-688) performs a multiplication on the result of a division:
-transferToAddressETH(marketingAddress,transferredBalance.div(_liquidityFee).mul(marketingDivisor)) (#686)
Consider ordering multiplication before division.

RepublicOfDogs.addLiquidity(uint256,uint256) (#734-747) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#739-746)
Ensure that all the return values of the function calls are used.

Additional information: link

RepublicOfDogs._approve(address,address,uint256).owner (#620) shadows:
- Ownable.owner() (#163-165) (function)
Rename the local variables that shadow another component.

Additional information: link

RepublicOfDogs.setBuybackUpperLimit(uint256) (#917-919) should emit an event for:
- buyBackUpperLimit = buyBackLimit * 10 ** 18 (#918)
Emit an event for critical parameter changes.

Additional information: link

RepublicOfDogs.setMarketingAddress(address)._marketingAddress (#921) lacks a zero-check on :
- marketingAddress = address(_marketingAddress) (#922)
Check that the address is not zero.

Ownable.unlock() (#198-203) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#200)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#130-147) uses assembly
- INLINE ASM (#139-142)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#85-88) is never used and should be removed
Remove unused functions.

Additional information: link

RepublicOfDogs._previousLiquidityFee (#446) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.

Additional information: link

solc-0.8.4 is not recommended for deployment
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#130-147):
- (success,returndata) = target.call{value: weiValue}(data) (#133)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable RepublicOfDogs._maxTxAmount (#450) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#17)" inContext (#11-20)
Remove redundant statements if they congest code but offer no value.

Variable RepublicOfDogs._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#829) is too similar to RepublicOfDogs._transferFromExcluded(address,address,uint256).tTransferAmount (#787)
Prevent variables from having similar names.

RepublicOfDogs.slitherConstructorVariables() (#417-956) uses literals with too many digits:
- minimumTokensBeforeSwap = 200000 * 10 ** 6 * 10 ** 9 (#451)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

RepublicOfDogs.deadAddress (#422) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setBuyBackEnabled(bool) should be declared external:
- RepublicOfDogs.setBuyBackEnabled(bool) (#930-933)
Use the external attribute for functions never called from the contract.
