Malnourished Dog

Condition:

Underweight – can see spine, hips and ribs – will see if I can get her weighed today
Seems to have possibly had multiple litters of pups
Skin looks good – no visible sores, rash or injuries, some tiny scars
Coat is soft – no noticeable hair loss, no fleas, two ticks removed
Eyes, ears, gums, look healthy. Some tartar on teeth.
No acute distress – eating well, small meals during the day – chicken, rice, some kibble, bananas
GI – some diarrhea, no vomiting
Unsure of any underlying illness, has not yet been examined by vet
Pretty strong girl, considering! Has energy to take long walks and pull on leash.
Very sweet and affectionate temperament so far, is very clingy and wants to be with someone at all times
Has socialized well with adults, but has not been around children or other pets while with us
Does not know a crate, toys, chews, how to play, or any simple commands
Does walk off leash beside me, returns with a call
