My name is Lincoln!

Lincoln is about 5 years old. Origin is unknown he was found at a gas station near a wildfire in Washington. His tail had been clipped so he was probably intended for herding. He is very sweet and can be protective. Takes a minute to warm up to strangers. House trained and somewhat leash trained. He seems to have some trauma but I’m not sure. He has a hard time with our floor because he is afraid of sliding. I believe it would be difficult for him to acclimate to other pets. We tried to socialize him once and he cowered in the corner. We are unequipped to care for him at this point and it breaks my heart to think that he might be taken to the pound. He needs some loving attention but we have a newborn and a toddler who terrorizes him and seems to be allergic.
