Each breed has different coat characteristics and this will have an effect on how much time they’ll need for grooming.
A double-coated, a thick-coated or heavily-coated dog comes with very high grooming need that will entail daily brushing, combing and cleaning.
Some might even need professional dog groomers if you are not experienced at grooming.
It is important for both you and your new friend that you are realistic with the amount of time and/or money you are prepared to expend.
