I self trained my family Dogs since they were just 2 months old. The biggest achievement: they can go to the toilet themselves and are very obedient. We also took in a street cat about 3 years ago, which we then have given a lot of care for. Very experienced with energetic dogs, since my dogs are beagles and are known to be the most hard-headed in the whole history of hard headed dogs 😃. Also experienced with puppies, can help teach a trick or two, no guarantees tho, because every pet has their own different preferences. Mine for example, are very food motivated.
