Dog Health Questions: Should I change dog food from wet to dry? in UK?

I have 3 years old female small sized border collie (a slightly bigger than jack russells size). She has lost awful of weight for not eating her food while I was away for my guide dog training for 2 weeks, a relative tried to make my pet dog to eat.. don't jugdement!. its not my relative's fault, they did everything they could she still would not eat, she just missed me so much. so when I got back home with new guide dog, my pet dog was really happy to see me be back home and made new friend with my guide dog and, she started eating well again. so I noticed my dog got alot thinner and I don't think wet food is good for her, I am thinking to switch dry food for my dog to lamb dry food for small breed, would it help her to grain weight? as my dog is only 10kg I could feel her ribs and spinal

since, she has started to eat normal again for 2 months, she still haven't grained any weight on

I feed her twice a day

Recommended Answer:
Since it has been quite some time I would recommend you take her to a vet. She may have an underlying condition affecting her weight. Explain the situation to your vet.
