I have a 4 year old, pit pug mix who I have had since she was 2 months old. I can do a little bit of training based on my experience with my dog; however, I’m not certified. However, I’ve been taking care of my dog for years and helping my friends by babysitting their dogs as well. I have bathed, groomed, trimmed nails, and regulated my dog’s diet since she was born. So I understand if your dog has special dietary needs. I’ve also have had dogs when I was younger in age, but at the age of 14 is when I got more attentive to what a dog actually needs. I have also volunteered at my hometown’s Humane Society, for 5 weeks straight. This is where I got more experience with walking and pet sitting other dogs besides my own.
