I grew up with dogs and cats and consider them apart of the family. I even shipped my two dogs and two cats from Guam to Mississippi because they are very important family members. I will be available to check on your dogs in the morning and evenings weekdays/weekends. Doesn't matter the size of the dog, and big dogs are not a problem. I have a Pit Bull myself, so I am not afraid of Pit Bulls, Rottweilers, German Shepherd or Doberman Pinscher. Their just big puppies who need more attention. I will also check on cats and give them attention, if they choose to want attention and acknowledge my existence. I'm available to walk dogs in the evening and make sure they get some fresh air.
