Hello Brandon…well done for giving this dog a home.
Firstly you really do need to take her to a Vet. Not only to see if she’s microchipped (she may actually belong to a worried owner) but she is obviously not in good health and needs checking over. All new pets should be checked by a Vet within the first 3 days of getting them.
That said she needs worming and a flea treatment, also heart worm meds if they are prevalent in your area. She needs a top quality food, small meals and often. Split her daily allowance between 4 or 5 meals to start with, as she gains fitness and body weight you can gradually knock them down to a meal morning and evening.
Glucosamine is a good bone/joint supplement as is Wild Salmon Oil which will also improve her skin and coat.
I do hope you and take her to the Vet as that is honestly what she needs. If she hasn’t been spayed it would be a good idea to have her done
Good
Just took him to the vet, and they found that the scratch on his tail was bigger than we thought and the thing sticking out was nerve tissue!
Fortunately they bandaged him up, gave him an antibiotic, and he’s going to be okay.
