One is a dog, one is a coffee maker…
lilmod, if a dog sank its teeth in you that is not exactly a good indication. You should have had enough Torah learning and mitzvos that the dog should have been even a bit respectful. The fact it had no fear of you…
Hmmm…
Sefer Kav Hayashar tells of an incident during the time of the Arizal where a woman did adultery and when the adulterer man died he came back as a dog and tried very hard to get inside her house. The pious husband kept hitting it and driving it away. One day he forgot to lock the door properly. The ugly looking dog leaped in and found the cheating wife in bed. Fell upon her and bit her repeatedly until they heard her shouting from the Arizal’s house.
Perhaps that dog had an issue with you in some way? Dogs just don’t touch any person.
Be that as it may, a contrite heart and mitzvos will always protect a person and change a decree for the better. Nothing to worry about! Reading the Chofetz Chaim each morning is excellent par excellence, especially the new Israel Book Shop publication one.
